$ /opt/gcc-trunk/bin/g++ -std=gnu++0x -Wno-pmf-conversions -fno-deduce-init-lis t -O3 -DNDEBUG -Wall -Werror -Wno-unused -msse -msse2 -march=native -mfpmath= sse -fomit-frame-pointer -c -ggdb texture.cpp.i However, it is very hard to replicate the error. It is fully deterministic, but occurs on [gcc version 4.5.0 20100322 (experimental) (GCC)] -- a month older compiler does not fail. It also doesn't happen without -ggdb. It requires an SSE4.1-capable processor (mine is Core i7), but occurs only when -march=native -- if I specify no march and explicitly enable -msse4, it also doesn't fail. I don't know what exact command line without -march should look like to cause the bug. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43508
