I'm trying to troubleshoot a game crash under Wine. Here's a snippet from the log file created under Wine 1.3.20: Code: wine: Unhandled page fault on read access to 0x00000000 at address 0x44a179 (thread 0022), starting debugger... Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x0044a179). Register dump: CS:0023 SS:002b DS:002b ES:002b FS:0063 GS:006b EIP:0044a179 ESP:0033fcd4 EBP:000001a0 EFLAGS:00010246( R- -- I Z- -P- ) EAX:00000000 EBX:00000000 ECX:0000000f EDX:00000000 ESI:0088555c EDI:00885520 Stack dump: 0x0033fcd4: 00000020 00000020 000001a0 00000240 0x0033fce4: 00a693f0 004f2173 0044a396 00000000 0x0033fcf4: 00000000 004d3efe 00000000 00000006 0x0033fd04: 00000006 3cc67e58 0089c1d0 0089c200 0x0033fd14: 7eb5a800 004d4141 00000000 7eb61b70 0x0033fd24: 0033fe90 0089c1c0 7eb5a8a0 3cc67e58 Backtrace: 0x0044a179: cmpw %bx,0x0(%eax) I don't have a clue what is causing the crash. With the above information is there anything I can do to determine if this is an issue with Wine? I just did a fresh install of the new Ubuntu (64 bit) release last week so I have a relatively clean environment. It might be distro related but honestly I can't tell either way at this point. Can anyone tell me what's happening at 0x0044a179?
