Bus Error

This may belong in the C Programming forum, but here goes anyway...

What would cause a bus error? I searched google for a cause, but came up with some conflicting reports...
Could it be caused by [lack of] disk space?
A lot of the pages I found mentioned linking with the incorrect versions of the library. But in that case, would it compile correctly?

Basically, I am curious as to why we had a job dump core on a bus error. It ran nearly to normal completion time, then simply poo-pood.

In the case that it may make a difference, it's a job that interfaces with an Oracle database on HP-UX 11. The things that had changed were that the process was recompiled, AND we were at 96% (df -k) on that disk...

Not too important for me to know right now, but I am curious, and who wants to wait for developers to tell me what happened? Smilie
