--- Comment #8 from Ken Thomases ken@codeweavers.com --- Created attachment 59322 --> https://bugs.winehq.org/attachment.cgi?id=59322 Patch to ignore access violations to get a macOS crash report
The best thing would be to do that regression test.
As for logging channels, it's hard to know what useful ones would be with so few details. A +tid,+relay,+seh log may be informative, but it will be huge and full of unrelated noise and thus hard to analyze.
Another possible approach is to build with the attached patch applied. It will make it so that neither Wine nor Skyrim can catch the crash. Instead, macOS will catch it and generate its own crash report. That crash report may be informative. On the other hand, the patch may break things so that Steam or Skyrim no longer even get to the point of the crash we're trying to diagnose. If that happens, then back it out.
