概 要openSUSE 11.1/gcc 4.3.2でOPTIMIZE=3設定時のコンパイルエラー。
詳 細On openSUSE 11.1 (32-bit) I get the following error (warning, treated as an error) with OPTIMIZE=3:

...
Compiling src/emu/input.c...
cc1: warnings being treated as errors
src/emu/input.c: In function ‘input_device_add’:
src/emu/input.c:1664: error: array subscript is below array bounds
make: *** [obj/sdl/mame/emu/input.o] Error 1

It works with OPTIMIZE=0, though.

Quoting couriersud:
(see http://www.bannister.org/forums/ubbthreads.php?ubb=showflat&Number=46957&page=2)

"Here is the offending code:

int symmetric = (colnum >= 5);
UINT8 val = map->map[rownum][symmetric ? (8 - colnum) : (colnum - 1)];

And it is not a compiler bug. For colnum==0 val=map->map[rownum][0 ? 8 : -1]."
再現手順Simply use a standard compile for 32-bit (no make options) - not sure about 64-bit builds, though. The 64-bit build worked fine on openSUSE 11.0 at least (gcc 4.3.1).
