I am trying to output a backtrace in a signal handler (for sigquit and sigsegv) in an ARM application on an embedded platform. It appears that two different approaches can be used, backtrace in glibc and using libunwind. In fact the Ltest-bt included in libunwind looks like a perfect example of what I am trying to do. However it does not seem to be working for me, it outputs:

Are you using the latest stable version (0.99)? If so, could you try --enable-debug-frame?

If it still doesn't work, please compile with --enable-debug and check the output of:

UNW_DEBUG_LEVEL=xx ./your-app
