Matt Fago <fago at earthlink dot net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |fago at earthlink dot net --- Comment #12 from Matt Fago <fago at earthlink dot net> 2013-01-14 19:35:43 UTC --- FYI, I recently ran into this issue as well building gcc 4.7.2 on MacOS 10.7.5 with XCode 4.1 installed. Configured via: ../gcc-4.7.2/configure --enable-languages=c,c++,fortran --enable-lto \ --program-suffix=-4.7 --enable-checking=release This command will use Apple's gcc 4.2.1. Bootstrap fails due to an ICE (I believe during the glibc build). First setting: export CC="gcc-4.4" export CXX="g++-4.4" fails with the error described in this bug report, while including -D_FORTIFY_SOURCE=0 in the above exports allows gcc to bootstrap.
