Should I report it? Most CPUs can access individual bytes from each memory address, but they generally cannot access larger units (16 bits, 32 bits, 64 bits and so on) without these units being "aligned"

Have you passed a scalar to an array or an array to a scalar? Another possible cause is an argument list in a call statement that does not contain the same variable types as the subroutine declaration.

If you have support for your product, you can open an issue at http://premier.intel.com. Among the possibilities are that the Core Duo fails immediately on faulty code which appears to run OK on other processors.

It just point back to the same article. If no other hardware responds, the CPU raises an exception, stating that the requested physical address is unrecognized by the whole computer system.

We are conjoined twins. I also have source code of NAG 19 fortran library coming from an old Alpha computer that I have compiled on this Mac computer using Intel Fortran. The new option will be in the F90 3.7.1 version tentatively scheduled for March 2015 release. For example, for hardware based on the IBM System/360 mainframe, including the IBM System z, Fujitsu B8000, RCA Spectra, and UNIVAC Series 90, instructions must be on a 16-bit boundary, that

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. Example[edit] This is an example of unaligned memory access, written in the C programming language with AT&T assembly syntax. #include int main(int argc, char **argv) { int *iptr; char *cptr; that use 'include ' in the declaration . Unaligned access[edit] Most CPUs are byte-addressable, where each unique memory address refers to an 8-bit byte.

based on MAC address -- why not "based on MAC addresses"? command statement return end the command statement should be ok . I've isolated it to simply this assignment. Source 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

The three most common errors are segmentation violations, bus errors, and arithmetic exceptions. Paging errors[edit] FreeBSD, Linux and Solaris can signal a bus error when virtual memory pages cannot be paged in, e.g. How do I convert text to datetime? Arrays in Fortran must have integer subscripts whose values are between 1 and the dimension of the array the subscript refers to.

Or have you passed a non-character argument to a character dummy? Browse other questions tagged parameters fortran bus-error or ask your own question. Since an infinite value cannot be represented by the computer, an error occurs. Do you have the correct number of arguments?

I had set ulimit -s unlimited and ulimit -d unlimited. Not a member? The code ran to apparently satisfactory completion on an earlier model, yet the use of a clobbered address produced immediate failure on the newer CPU. The rest of my code works without error.
