I get this while compiling the Latest SVN, but only if I use OSD=winui

Code:
make TARGET=mess OSD=winui
Compiling src/mess/video/pdp1.c...
src/mess/video/pdp1.c: In function 'void pdp1_draw_panel(running_machine*, bitmap_t*)':
src/mess/video/pdp1.c:306: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [obj/winui/mess/mess/video/pdp1.o] Error 1

Compiles fine if I drop the OSD=winui
