--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, message for me is:

$ /usr/local/bin/g++ -c -Wall -Wextra 81761.cc
/var/tmp//ccqm9pwP.s:85:FATAL:Symbol __ZZ3foovE8__func__ already defined.
$

Removing targets because it also happens for me on i386-apple-darwin9.8.0, so
it's not specific to the ones you listed.

(also it'd be nice to improve the testcase to have an explicit __func__ in it,
instead of relying on the expansion of assert() to contain one)
