There are at least 2 fallouts: 1. -mx32 is broken. 2. libsanitizer now depends on libm: sanitizer_common/sanitizer_common_interceptors.inc:extern int signgam; sanitizer_common/sanitizer_common_interceptors.inc: COMMON_INTERCEPTOR_WRITE_RANGE(ctx, &signgam, sizeof(signgam)); sanitizer_common/sanitizer_common_interceptors.inc: COMMON_INTERCEPTOR_WRITE_RANGE(ctx, &signgam, sizeof(signgam)); sanitizer_common/sanitizer_common_interceptors.inc: COMMON_INTERCEPTOR_WRITE_RANGE(ctx, &signgam, sizeof(signgam)); But -lm is added for -fsanitizer=address and I got configure:3158: /export/build/gnu/gcc-asan/build-x86_64-linux/./prev-gcc/xgcc -B/export/build/gnu/gcc-asan/build-x86_64-linux/./prev-gcc/ -B/usr/local/x86_64-unknown-linux-gnu/bin/ -B/usr/local/x86_64-unknown-linux-gnu/bin/ -B/usr/local/x86_64-unknown-linux-gnu/lib/ -isystem /usr/local/x86_64-unknown-linux-gnu/include -isystem /usr/local/x86_64-unknown-linux-gnu/sys-include -o conftest -O2 -g -fsanitize=address -static-libstdc++ -static-libgcc -fsanitize=address -static-libasan -B/export/build/gnu/gcc-asan/build-x86_64-linux/prev-x86_64-unknown-linux-gnu/libsanitizer/ -B/export/build/gnu/gcc-asan/build-x86_64-linux/prev-x86_64-unknown-linux-gnu/libsanitizer/asan/ -B/export/build/gnu/gcc-asan/build-x86_64-linux/prev-x86_64-unknown-linux-gnu/libsanitizer/asan/.libs conftest.c >&5 /export/build/gnu/gcc-asan/build-x86_64-linux/prev-x86_64-unknown-linux-gnu/libsanitizer/asan/.libs/libasan.a(asan_interceptors.o): In function `__interceptor_lgamma': /export/gnu/import/git/gcc/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:2762: undefined reference to `signgam' /export/build/gnu/gcc-asan/build-x86_64-linux/prev-x86_64-unknown-linux-gnu/libsanitizer/asan/.libs/libasan.a(asan_interceptors.o): In function `__interceptor_lgammaf': -- H.J.
