Backtrace Of Linux Core Dump With No Debug Info In It.?
I have a core dump file that has been generated in production
environment – there is no debug info in it. Backtrace in gdb doesn’t
show any useful information.
Is there a way with gdb or with some other tool to get assembly
backtrace?

It’s pretty tough to generate a backtrace if the
code was not only compiled without debug, but
more to the point, with the frame pointer optimized
away. If “gdb” or “pstack” can’t give you a backtrace,
then you’re in a tough spot.
If you have any control over the building of the
application (for the future), have the developers
specify flags to gcc to use the FP (rather than
optimizing it away by only using offsets from SP).
