It will, of course, vary between compilers, but this is what clang generates: $ cat static.c _Static_assert(0, "example assert failed"); $ cc static.c static.c:1:1: error: static_assert failed "example assert failed" _Static_assert(0, "example assert failed"); ^ ~ 1 error generated. GCC 4.8 and later produce very similar output: $ gcc-4.8 static.c static.c:1:1: error: static assertion failed: "example assert failed" _Static_assert(0, "example assert failed"); ^ gcc 4.7 only provides the first line: $ gcc-4.7 static.c static.c:1:1: error: static assertion failed: "example assert failed" David
