--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> --- If the warning is based of a const, maybe lead with that e.g. in the 2nd place here: bug.c:11:5: warning: 'memset': specified size 18446744073709551611 (aka 0xffff_ffff_ffff_fffb, 1<<64 - 5, SOME_CONST) exceeds maximum object size PTRDIFF_MAX (aka 9223372036854775807, 0x7fff_ffff_ffff_ffff, 1<<63 - 1)
