#2 It doesn't work on macOS

Tested on macOS Ventura 13.1 with Wine 8.4 staging build

With patch:

1447042.202:01fc:err:virtual:virtual_setup_exception stack overflow 1648 bytes addr 0x170033490 stack 0x110990 (0x110000-0x111000-0x210000)

Without patch: (just for reference

1447019.533:01c0:fixme:thread_:get_thread_times not implemented on this platform
1447019.762:01c4:fixme:ver:GetCurrentPackageId (00000000026FFE10 0000000000000000): stub

btw I can't star this repo as it always gives me 404. not a bug?

Also tested on foss crossover 22.1 (based wine 7.7) with patch. Although it's not supposed to work, at least it generates unity crash logs (and the wine log is similar to 8.4 without patch, and there is no err:virtual:try_map_free_area. The game runs in background for minites and crashes, no window pops up). I upload it here for reference. crash.tar.gz.

notabug is literally broken

The 7.7 crash is reproducible on my system. Seems like the 8.4 Wine build for macOS is just broken

wine log with trace WINEDEBUG=trace+all,+relay

Seems like this Wine build doesn't replicate the Windows thread environment block correctly. Unfortunately there's nothing I can do about it.

0x0000018019c708 causes the c0000005 error and for some reason the error handler creates an infinite loop (seems error is raised the handler and be handled the handler again)

There is no wine log (trace or relay) after entering 0x1400a5b1f

The instruction at 0x0000018019c708 is supposed to get the process environment block address from the thread environment block. Reading the TEB causes an access violation (c0000005) for some reason. That's why I made the assumption that this Wine build doesn't replicate the Windows TEB correctly

No, it is actually supposed to get the InMemoryOrderModuleList from the Ldr structure in the PEB. https://learn.microsoft.com/en-us/windows/win32/api/winternl/ns-winternl-peb_ldr_data

For some reason that causes an access violation. It really shouldn't.

with these patches problem get solved.
