Re: concurrent computation of a function

Hi Bill,

Would compiling GP with debugging info and checking the crash backtrace help here?

If so, I'd be interested to step in debugging the issue.

Max

This is exactly the kind of problems I warned you about.
To fix this we would need to know exactly what line of C
code was executed when the process was interrupted.
This is very hard to come by.
