Confirmed.  Of course the testcase is somewhat "invalid".  Since GCC 4.7

we preserve the original function type that is in effect for performing the

call but we are able to still propagate the actual function decl to the

call stmt.  Code inspecting arguments based on the fact the called function

is a builtin decl needs additional verification now ...



Mine.
