--- Comment #3 from andreas at galauner dot de 2011-07-13 22:09:11 UTC --- I just compiled GCC 4.6.1 again without clang after I found out how to do that. By defining CC = /usr/bin/gcc-4.2 CPP = /usr/bin/cpp-4.2 CXX = /usr/bin/g++-4.2 LD = /usr/bin/gcc-4.2 before the configure step the Apple GCC is used for compilation. If you don't do that, clang will be used on Mac OS with XCode >4 and this leads to this "internal compiler error". So, it doesn't seem to be a GCC issue.
