--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-02-08 14:32:13 UTC --- I don't see how a libasan change could cause a "miscompilation" of gengtype. Anyway, I've rebuild build/gengtype* with rm -f build/gengtype* make CXX='./xg++ -B ./ -fsanitize=address `../x86_64-unknown-linux-gnu/libstdc++-v3/scripts/testsuite_flags --build-includes`' build/gengtype LD_LIBRARY_PATH=../x86_64-unknown-linux-gnu/libsanitizer/asan/.libs/ build/gengtype -S ../../gcc -I gtyp-input.list -w tmp-gtype.state and it works just fine.
