Thanks for your answer.

I'm interested in ARM/THUMB debugging.  Currently I use GDB 4.17 (from
Cygnus GNUPro 98r2) with PE-COFF/STABS.  With that configuration backtrace
does not work if the involved functions are frameless.  I was wondering
whether the situation would be improved by using a more recent version of
GDB and/or ELF/DWARF.

I looked at the ARM backtrace code in the GDB CVS repository a couple of
months ago and it seemed quite similar to GDB 4.17 but I may be wrong.
