C and C++ programmers can also use 'gdb'. Just for a sanity check, find a system exerciser - perhaps a LINPACK or some other memory/cpu intensive app and run it for a day to stress the system. it stop execution and came out :bus error 10 . To debug it yourself next time, compile with -g option, like this: $ gfortran -g code.f95 and run it under a debugger: $ gdb a.out gdb> run it will then give Check This Out
A bus error occurs if the data sets passed during a main/subprogram to subprogram interface are not of equal size. Common fortran error messages When you execute your program, you may encounter run-time errors that are difficult to trace. And just to be sure, you did you use Intel for compiling the NAG library and your application? I spent the time of several people on such a situation, where an array over-run clobbered the stack.
Have you passed a scalar to an array or an array to a scalar? Can my employer see what I do on the internet when I am connected to the company network? Say for example you have a common block common /x/ i,x(10),j,y(20) where i,j are default sized integers (4 bytes) and x and y are double precision (default You should not leave file in /tmp when you logout.
This happened quite a bit with the older SGI compilers (from IRIX 5.3 days and before). This is the area of the disk that the machine uses for virtual memory. Only really useful for debugging the GNU Fortran compiler itself. -fdump-parse-treeOutput the internal parse tree after translating the source program into internal representation. The call from main was a test line of code using a constant.

Please be considerate of other users. The last possibilty: I have seen bus errors RARELY with a bad CPU or the seating of the CPU.
of D&D? This edition retains the conversational style of the original, along with its simple, carefully chosen subset language and its focus on floating-point calculations. Netscape Bus Error 9. Do paper books exist in the 5th ed.
Bus Error? 4. share|improve this answer answered Apr 12 '11 at 23:27 ifeitosa 562 I moved it above the loop and it works now. Should I be concerned about "security"? Unlike bytes, larger units can span two aligned addresses and would thus require more than one fetch on the data bus.
short *sptr; int i; sptr = (short *)&i; // For all odd value increments, it will result in sigbus. http://alltechgossip.com/bus-error/bus-error-10-fortran.html From your questions so far you seem to be learning an antiquated version of Fortran, more recent versions provide the necessary features to write much safer programs. –High Performance Mark Dec Search Restricted Search Archived Admin Options: Edit this Document Engineering College of Engineering First Year Engineering Schools & Programs Information Technology Engineering Computer Network Information Technology at Purdue Purdue Purdue Homepage Promote this comment to an answer, and I'll select it as the winner. ;) –Old McStopher Dec 13 '10 at 12:24 I'm not sure if I want to "win"
How do I get the last lines of dust into the dustpan? This error commonly occurs when one attempts to divide by zero. share|improve this answer edited Apr 12 '11 at 23:26 answered Apr 12 '11 at 23:20 Jim Lewis 27k45279 add a comment| up vote 4 down vote Your allocation of temparray is http://alltechgossip.com/bus-error/bus-error-fortran-90.html that use 'include ' in the declaration .
You should delete the "core" file when you don't need it any more. Just move the line ALLOCATE(temparray(numrolls)) before you enter the loop. Example This is an example of unaligned memory access, written in the C programming language with AT&T assembly syntax. #include
Does Harley Quinn ever have children?
Bus Error: Chicken 0.990 on SunOS 5.7 on Sparc 8. Thanks so much! A common example in C is: int c; scanf("%d", c); instead of the correct version: int c; scanf("%d", &c); An example from C++ is: int* p=new int; cout<< p; instead of BE CAREFUL not to let yourself go over quota, as you would then not be able to create or edit files.
Another question I have is do you know how I can fix the part PRINT*, "Experiment ",i which is in the loop right below the allocate statement so that it prints Printing the low order bits of the address shows that it is not aligned to a word boundary ("dword" using x86 terminology). Categories Search Type in a few keywords describing what information you are looking for in the text box below. navigate here Have you messed up argument type--for example passing a single precision to a double precision argument?
Help - Ruby 1.8.0, Mac OS X, AEOSA = bus error - one more time 6. Close Box Join Tek-Tips Today! Class armor proficiency vs. If the co-signer on my car loan dies, can the family take the car from me like they're threatening to?
I've implemented many write commands to find the error more > exactly - but it was not succesfull. For example, if you declared an array as: real foo(10,5) and attempted to access element foo(32,3), a segmentation violation may occur because the value 32 is greater than the dimension of I've implemented many write commands to find the error more exactly - but it was not succesfull. Then if the compiler choses a naive packing of the variables in memory, the double x will be offset by 4 bytes, and usually will cause a bus error, though the
Accordingly, the CPU sets this physical address on its address bus and requests all other hardware connected to the CPU to respond with the results, if they answer for this specific For example, the code: integer i,j,k i = 1 j = 0 k = i/j will generate the error "Arithmetic Exception: Integer divide by 0" because an attempt to divide by I should have access to this address, as it is declared in the parameter list, unless Fortran does not allow parameters to be modified without some special declaration.

i will try use pointer represent ,try use free () to release the memorary . Why secure web services? For example, if multi-byte accesses must be 16 bit-aligned, addresses (given in bytes) at 0, 2, 4, 6, and so on would be considered aligned and therefore accessible, while addresses 1, Then you can type, say: limit coredumpsize 100 ..

Countries where lecture duration does not exceed one hour Texas, USA speed ticket as a European citizen, already left the country Is it a stochastic matrix?
Core dumps created this way will not take up quota, and they will automatically vanish when the machine is rebooted.
