E.g. something like that in src/sna/compiler.h: --- a/src/sna/compiler.h +++ b/src/sna/compiler.h @@ -63,7 +63,7 @@ #define sse4_2 __attribute__((target("sse4.2,sse2,fpmath=sse"))) #endif -#if HAS_GCC(4, 6) && defined(__OPTIMIZE__) +#if HAS_GCC(4, 6) && !HAS_GCC(5, 0) && defined(__OPTIMIZE__) #define fast __attribute__((optimize("Ofast"))) #else #define fast But I do not think this is something suitable for upstream as the bug lies in gcc, so it's just a workaround until the issue is fixed in gcc.
