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

Hi,
If you are on Solaris then
$dbx core <ProC exeName>
Now it will read all the related shared libraries and stop at the dbx prompt. Now where should show you the path of execution of the executable and where it formed the core.
dbx>where
Check for the Null pointers where in the first line (last step). Then you can go up and up and print the *this pointer to check what parameter is being passed and why it is killing..
Cheers
Baral
