Hi, form your stacktrace I can only see that the crash didn't happen in GnuGk, but in a PWLib container. If you compile GnuGk with 'make debug' we could see which GnuGk function calls lead up to the crash and we may be able to see if its a bug in GnuGk or PWLib. Does the trace file give any clues what happened ?
