Unhandled exception: unimplemented function winegstreamer.dll.winegstreamer_create_wm_sync_reader called in wow64 32-bit code (0x7b5f8fe8).
Disregard again for now.
This backtrace may be a red herring for my particular shared wow64 build because I skipped 32 bit winegstreamer because it's one of the few Debian apt packages that causes the 64 bit versions to be uninstalled.
Previously I uninstalling 64-bit gstreamer for building 32-bit shared WINE and reinstalling 64-bit gstreamer for building 64-bit shared WINE.
This highlights the convenience that new WoW64 provides but as stated before share WoW64 is still being used by many downstream projects which may still need to be supported until they migrate to new WoW64.
I'll fulfilling the 32-bit gstreamer parts missing for my shared WoW64 and retest.
