What version of GDB are you running? Some time ago, there were various threads
in both lists(devel/user) about GDB showing only the last frame in all
backtraces. The bug was tracked down... and it came from binutils, IIRC(the
proposed fix was a workaround in GDB). Maybe it is appearing here in a
different form.
