--- Comment #8 from Paul Gofman <pgofman at codeweavers.com> ---
This is my patch from official Proton, where it got to GE custom probably and
where it has proper subject and authorship.

The background of the issue is that .Net 6 has its own replacement for
RtlRestoreContext. Wine uses a workaround for own exception handlers on x64:
using TIB handlers just like on i386 and pops them in RtlRestoreContext. When
the handkers are not popped they are erroneously used later with unrelated
stack contents. My patch adds the functionally correct handling of that for
exception processing part, although it is not a complete solution as there are
more Wine handlers which are not fixed by this patch. Upstream solution is
waiting fir proper .seh exception handling support by compiler.
