Eric Gallager <egallager at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target|powerpc64le-*-linux, | |x86_64-*-linux | Status|UNCONFIRMED |NEW Last reconfirmed| |2017-08-11 CC| |egallager at gcc dot gnu.org Ever confirmed|0 |1 --- 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)
