Dbx: internal error: signal SIGSEGV

Question

Hi All,
Using Sun Studio to build our C/C++ (with boost) application. When I try to debug with dbx I get:
dbx: internal error: signal SIGSEGV (no mapping at the fault address)
dbx's coredump will appear in /tmp
Abort (core dumped)
Can anyone suggest a solution? More details follow.
thanks
Scott.

You have found bug in dbx. We would appreciate if you file it using bugs.sun.com or provide a testcase, in which case I'll file it myself. If you can't post source code here, maybe you can send binary on which dbx crashed to me by email - kms at sun dot com?
Thanks,
Maxim.
