--- Comment #6 from vv221 accounts.winehq.org@vv221.fr --- This behaviour being reproducible with wine-staging ntdll-WRITECOPY patchset might point to it being related to https://bugs.winehq.org/show_bug.cgi?id=29384
I checked the Debian patchsets, and there is indeed one patch related to #29384 (see attachments). I am going to check if building the Debian package without this patch is enough to get rid of the crash.
