Hi
Buildfarm machine lyrebird, clang 2.9, amd64, Debian 6, 'HEAD'. I
have been unsuccessful in finding out what it's doing using gdb:
pg_animal@asterix:~/work/HEAD/pgsql$ gdb --pid=10681

Asking GDB anything generates similar messages. It seems like this
might be related to a known clang/dwarf/gdb bug (apparently
experienced by many MacOS users and the Chromium project, based on
cursory googling), and possibly not related to whatever difficulty
pg_regress is having. So I don't actually have anything useful to
report here unfortunately... but thought I should write a note since
I'll suppose when I kill it it'll show up as a failure. Unfortunately
I don't have time to dig further currently.
