--- Comment #1 from mata sutupud@yahoo.com --- Created attachment 68361 --> https://bugs.winehq.org/attachment.cgi?id=68361 DDO startup crash fix patch
Update: It's still happening on wine 5.18, up to the current master (5d5102f8498413f4b7e11f7da0509e7717fb3735)
The problematic code is definitely in call_user_apc_dispatcher dlls/ntdll/unix/signal_x86_64.c
If I change the code to more or less what it did before a686759f1d7aee67b5786b72e81a4e4fcf3f3c02 (see attached patch), then it starts to work again (despite a compilation time warning: wine-git/dlls/ntdll/unix/signal_x86_64.c:2023:1: warning: ‘noreturn’ function does return).
So something seems to be not completely right in the assembly code.
