--- Comment #6 from Mark Millard <mar...@dsl-only.net> ---
(In reply to John Baldwin from comment #5)

I've used both gdb's as well but I've had more
occasions when system's gdb worked and ports
did not than the other way around (when there
is a distinction). (Historically, not just
now.)

Okay I'll poke at ps -M and the /usr/local/bin/gdb
crash.

Be warned: I'm also currently evidence-gathering
for two folks working on the clang powerpc and/or
powerpc64 targeting support so my FreeBSD
time is split.

This also leads to context switching between a
world built with gcc 4.2.1 and one built with
clang. If I'm interrupted I can forget to switch
and, for example, end up seeing the clang issues
without initially noticing why (clang built
system libraries, for example).

I'll rerun the /usr/local/bin/gdb test explicitly
on a gcc 4.2.1 built world just in case that
happened yesterday.

(clang generates powerpc and powerpc64 "code" that
has handling of thrown-C++-exceptions completely
broken, leading to segmentation faults while trying
to reach landing-pad code. "Code": incomplete dwarf
information.)
