The glibc 2.1 backtrace on i386 only works when compiled without
-fomit-frame-pointer, and it does only resolve dynamically exported
symbols (so that the rest is left for addr2line). Extending it to
read the dwarf2 exception tables would be definitely a worthy goal,
to get accurate backtracing information even without standard stack
frame.

Is there a standard way on how user code can access these unwind 
tables without messing with libgcc2 internals?
