Bus Error Fortran 90
We know nothing about row and column values... This happened quite a bit with the older SGI compilers (from IRIX 5.3 days and before). Living on an Isolated Peninsula - Making it Impossible to Leave Can guns be rendered unusable by changing the atmosphere? To answer your question "what is a bus error?" : it generally means that your program tried to access a nonexistent address, or an address that doesn't have the proper alignment have a peek here
Like you, I think a bus error is usually an attempt to address memory which doesn't exist. the program call subroutine in a loop. Not the answer you're looking for? For a good comment about bus error, see Segmentation fault.
i think something wrong with common block. I don't see how I'm pointing to non-existant memory. Bus Error? 4. The Intel Fortran Compiler use stack space to allocate a number of temporary or intermediate copies of array data.

I've implemented many write commands to find the error more > exactly - but it was not succesfull. This trace back report is read from the bottom of the list upwards. Find the uppermost subroutine or function from your code along with it's line number to isolate which instruction call ThisIsIllegal( some_arguments ) ... --- end main program --- --- ThisIsIllegal --- integer function ThisIsIllegal( some_arguments ) ... --- end ThisIsIllegal --- In the example above, the main program calls and what -O optimization did you use?
Is there a command for running a script according to its shebang line? In contrast, a "segmentation fault" is typically caused by accessing an address that exists, but which the program is not allowed to access -- see en.wikipedia.org/wiki/Segmentation_fault. 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 I'm running gfortran (not sure which version, off-hand) from the terminal in OS X.

An arithmetic exception can also occur if the value of a variable exceeds the largest value that can be represented by the corresponding data type.

non-existent physical address this is equivalent to a segmentation fault, but for a physical address rather than a virtual address. Browse other questions tagged arrays fortran bus fortran95 or ask your own question. Particularly, did you use -align? It just point back to the same article.
