--- Comment #8 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> ---
GCC 4.9, which has just been released, has -fsanitize=undefined (and some other
-fsanitize checks):
http://gcc.gnu.org/onlinedocs/gcc-4.9.0/gcc/Debugging-Options.html#Debugging-Options
However it only gives a runtime diagnostic message. It basically lacks clang's
-fno-sanitize-recover option to make the program abort (useful for test
suites). After that, I suppose that this enhancement would be complete (it
doesn't check all kinds of undefined behavior, such as the use of uninitialized
variables, but clang doesn't do this either).
