it still have this problem . non-existent physical address this is equivalent to a segmentation fault, but for a physical address rather than a virtual address.

I don't know what you mean by 'new standard'. Our program works well until the gcc upgrade. > Is this new standard? This is an example of register indirect addressing. Are basis vectors imaginary in special relativity?

Thanks a lot Norbert Wed, 18 Jun 1902 08:00:00 GMT Dick Hendrickso#2 / 3 bus error As I recall, bus error is usually Unix's way of signaling a bad address. 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.

SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it is normally caused by deer in German: Hirsch, Reh Composition of Derangements How common is it to use the word 'bitch' for a female dog? Replacing it with a declared INTEGER in the call, seemed to do the trick! Why can't the second fundamental theorem of calculus be proved in just two lines?

I use F77 on a SGI unix. Do you mean that only if the return value is character string, then it will be passed back through first argument (at '&rlat' posistion)? Some systems may have a hybrid of these depending on the architecture being used. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions.

Have you messed up argument type--for example passing a single precision to a double precision argument? What is an instant of time? This error commonly occurs when one attempts to divide by zero.
