Dbx core dumping

Question

dbx core dumping when I debug my application with RTC enable (I'm truying to dectect some memory leaks in my code). and I'm getting the following
RTC: Enabling Error Checking...
RTC: Running program...

Some iformation you might need:
Compiler : code compiled with cc version 6.2
Debugger : 6.2 patch 111683-03

/export/home/husam/release/lib/libstorage_s.so.1:backend.c stab #530 host:(0,211),The key to your problem is probably the stabs reading error.
How was backend.c compiled?
Normally dbx will load stabs information on demand as needed.
You can start dbx and use the "module" command to load
the stabs information right away without running the program or using RTC.
Try this:
(dbx) module backend.o
Does that cause the stabs warnings?
If you can "repair" or "normalize" the stabs information in that module,
the crash will probably go away.
