I completely agree that GDB's behavior is more useful than GCC's.
Having GCC generate a warning message for such expressions, or
(golly!) disable the extension to standard C that allows arithmetic on
function pointers for that ABI, sound much better to me.

The reason I hold up GCC as the reference implementation has nothing
to do with admiration of GCC. It is because the program the user is
trying to understand was compiled with GCC.
