Whenever I try to run a 16-bit application with the version of Wine that built out of MacPorts, I get a crash similar to this one: Code: wine: Unhandled page fault on read access to 0xffffffff at address 0x1017:0x0000093e (thread 0026), starting debugger... couldn't load main module (2) Unhandled exception: page fault on read access to 0xffffffff in 32-bit code (1017:0000093e). fixme:dbghelp:addr_to_linear Failed to linearize address 8714:00006f03 (mode 0) In 32 bit mode.

This doesn't happen when I run the same applications with a precompiled binary on Linux. I would file a bug report, but I have a suspicion that this is just a bad compile, as I've seen reports of 16-bit applications working on Macs that aren't MacPorts. Anyone have any insight? I've asked the IRC channel a few times, but no one there seemed to know.
