--- Comment #1 from Bernhard Übelacker <bernhardu at mailbox.org> ---
Created attachment 71344
  --> https://bugs.winehq.org/attachment.cgi?id=71344
Another backtrace with PDB file available.

The crash seems to happen because
"nsObserverService::AddObserver" contains a "NS_ENSURE_VALIDCALL".

This "NS_ENSURE_VALIDCALL" calls "NS_IsMainThread" which returns,
as far as I see "0".

Therefore this line gets executed:
   212          MOZ_CRASH("Using observer service off the main thread!"); \

This leads to the following line in wine-gecko-2.47.2/mfbt/Assertions.h
   235           *((volatile int*) NULL) = __LINE__; \

And this matches the crashing instruction:
   0x000000018007de47 xul+0x7de47: movl    $0xe3,0x0000000000000000

Maybe the MOZ_CRASH_ANNOTATE should output something to stderr in this case.
