Help: dbx core dump, solaris 10, amd64

Question

Hi,
Recently I run into the following when I debug a core dump,
(dbx) where
dbx: internal error: signal SIGSEGV (no mapping at the fault address)
dbx's coredump will appear in /tmp
Abort (core dumped)
-bash-3.00$ dbx -V
Sun Ceres DBX Debugger 7.7 SunOS_i386 2008/10/22
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.7' in your .dbxrc
(dbx)
I wonder if anyone has some idea of this bug, is it known? Is it fixed in sunstudio 12 u1?
If needed, I can supply /tmp/core dumped by dbx.
Thanks,
