Hi Richard,
The BUILT_IN_FREE was introduced in r138362 fixing PR36970,
in which gcc did not give warning on freeing non-heap memory, as in program:

main ()
{
     char array[100];
     free (array);
}

I will run make check to see whether it's ok we do not check
DECL_ASSEMBLER_NAME_SET_P and send a patch then.

BTW, should I create a bug for this?

Thanks.
