No.11574 B2K24 Senior Tester Apr 6, 2015, 16:42	Seems very likely since the segmentation fault can't be reproduced here. Do the other sets listed in 05911 also trigger the segmentation fault or is it just this specific set?
No.11576 NekoEd Senior Tester Apr 6, 2015, 17:10	No, it's just racedriv (clones not tested). The rest give the 05911 behavior upon F3 reset but that's not a bug (since MAME itself doesn't crash).

No.11640 Robbbert Senior Tester May 2, 2015, 22:00	Confirmed F3 crash with racedriv. Stun Runner works fine, but gives the GSP timeout a while after F3 pressed

I'm using the official mame 0.161 build 64-bit. mame crashes before I get into the game. The only one that's working is Hard Drvin' Airborne. All others just crash when I start the emu. Update: I just discovered that the cheat is causing the hard drivin' based games to crash so I had disable cheats before starting the game. It runs fine without the cheats turned on. http://snag.gy/1AxWz.jpg

No.11652 Osso Moderator May 6, 2015, 10:25	Commenting out line 296 of audio/harddriv.c makes the crash disappear, so the exact regression revision seems to be r17191.
