Here you go. This passes at -O0 but fails at -O2. Note that the testcase requires >= 7 args to the test function, to force the last arg to spill onto the stack; also an inner (non-inlined) function call, to force that single stack arg to be zero-extended to word size and overwrite the flags. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45677
