Bug #50271 might be related. Could you please try with the patch attached to the bug and if it is still crashing send me ntdll.so binary (https://bugs.winehq.org/show_bug.cgi?id=50271#c17)? In any case, output with WINEDEBUG=warn+seh could be helpful (the full log as suggested in the comment would be better, but not sure if it is easy with interactive winedbg run).
Thanks, the patch fixed it for me. Output of WINEDEBUG=warn+seh is attached. I will attach a log with +pid,+seh,+timestamp later.
