During emerge world on ~amd64 gcc-4.6.2 fails to build with the above error. Notes: 1) I had already installed gcc-4.6.2 while it was still masked (unmasked it, installed, then masked again) because a third-party software required GLIBCXX_3.4.15 ABI on libstdc++.so.6 2) There is a bug report on gnu.org that might be related: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50888 3) This also seems related: https://bugs.gentoo.org/show_bug.cgi?id=407651 Reproducible: Always #

I have tried unmerging the installed instance of gcc-4.6.2 - the error persists.
(In reply to comment #0) > 3) This also seems related: https://bugs.gentoo.org/show_bug.cgi?id=407651 OK, not sure about that anymore, given that the problem persists with 4.6.2 unmerged.
Please attach the entire build log to this bug report.
(In reply to comment #4) > Please attach the entire build log to this bug report. The file is 14MB. Unfortunately bugzilla won't let me upload it (limit seems to be 1MB). You can find it here: http://markus.wernig.net/files/gcc-4.6.2-build.log
OK, applying the patch from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50888 fixes the problem: gcc builds normally
