My Pro*C core dumps with a segmentation fault error. I was wondering if anyone knows a way to analyze the core dump file. More specifically: how to do a trace back of the core file in oder to get a stack trace or any sort of meaningful analysis?

Also, any tips on debugging a pro*c memory leak problem?

THANK YOU IN ADVANCE

Got the same thing today - sig 11. Not an expert, but you can try "strings core" and redirect to a file. Look thru here, especially at the end. Takes a while, and most stuff is not relevant, but the bugs usually show up (worked for me). Someone showed me you can use gdb to look at the call stack, and this was very useful, too. Determine exe that bombed. Go to location of core file. If file is named simply 'core', enter "gdb <fullpathname of exe> core". At 'gbd' prompt, enter 'ba'. Look at stack for offending module. Good luck!
