Sadly, buggy programs are not guaranteed to fail. Somewhere in your program is a bug and you need to find it. For example, maybe a pointer has a bad value, but you are using it to store something. This overwrites something that it shouldn't. When you staticly link the program, you may be stepping on something that you don't need. But generate position independent code, and now you're clobbering something important.
The good news is that you have found a way to reliably expose the bug. The next step is to remove the bug.
The illegal operation sounds like you nailed a return address on the stack.
And yes this sort of thing happens to me a lot, although it's usually a program that works on hp but not sun (or vice versa). And it's always a bug a in my code. For this reason, I try my program on both systems as a quality check.

Hi. Does anyone know by how much a text size of an executable(on ibm) would grow if you link one shared object(library)? Is it a constant number or it depends on a .so that is linked? (3 Replies)
