--- Comment #2 from d25fe0be@ <d25fe0be at outlook dot com> --- After suppressing Clang's error about passing POD through varargs, bootstrapping r251624 now fails with: ``` libtool: compile: /private/tmp/gcc-20170903-13173-cfn0kc/build/./gcc/xgcc -B/private/tmp/gcc-20170903-13173-cfn0kc/build/./gcc/ -B/usr/local/Cellar/gcc/HEAD-251624/x86_64-apple-darwin16.7.0/bin/ -B/usr/local/Cellar/gcc/HEAD-251624/x86_64-apple-darwin16.7.0/lib/ -isystem /usr/local/Cellar/gcc/HEAD-251624/x86_64-apple-darwin16.7.0/include -isystem /usr/local/Cellar/gcc/HEAD-251624/x86_64-apple-darwin16.7.0/sys-include -DHAVE_CONFIG_H -I. -I../../../../libgomp -I../../../../libgomp/config/bsd -I../../../../libgomp/config/darwin -I../../../../libgomp/config/posix -I../../../../libgomp -I../../../../libgomp/../include -Wall -pthread -Werror -g -O2 -m32 -MT iter_ull.lo -MD -MP -MF .deps/iter_ull.Tpo -c ../../../../libgomp/iter_ull.c -fno-common -DPIC -o .libs/iter_ull.o during RTL pass: expand ../../../../libgomp/iter_ull.c: In function 'gomp_iter_ull_static_next': ../../../../libgomp/iter_ull.c:40:1: internal compiler error: Illegal instruction: 4 gomp_iter_ull_static_next (gomp_ull *pstart, gomp_ull *pend) ^~~~~~~~~~~~~~~~~~~~~~~~~ libbacktrace could not find executable to open Please submit a full bug report, with preprocessed source if appropriate.
