Also, I might want to know whether it is common case that linux apps
are compiled with -fomit-frame-pointer swtich?
Thanks!

This is the Linux KERNEL development list.
Not Linux USERSPACE development list.
Find an appropriate list and ask your question there please.

Thanks for your reply.
But I am looking for a tool or method to do stack backtrace
automatically, not debug manually.
The tool listed on http://www.aivosto.com/visustin.html can only
generate control flow from source code. But I need a control flow
generator that can generate control flow from binary codes. One
example is EEL (Executable Edit Library). But it only works for SPARC
machine, not PC. :(
As for the question about the kernel development list, I am developing
a kernel module that supports stack backtrace and can analyze user app
binaries to enforce security policies. So this is still related to
Kernel development. :)

Barring gentoo/LFS/DIY distros, where no such assertions can be made, the
answer is probably "no". Most distros don't strip out a useful source of
userspace debugging for the sake of 'speed'.
