WINEDEBUG=+quartz,+wmp

Since the March 25, 2020 update of Magic Online client, quartz regularly
crashes in PullPin_Disconnect, whereas the following configuration is used:

winetricks sound=disabled winegstreamer=disabled

Attached is the backtrace, a +quartz,+wmp trace, and the wav file it was
playing. Relevant errors seem to be around:
0073:err:quartz:BaseMemAllocator_Commit fnAlloc failed with error 0x8004020e
0073:warn:quartz:FilterGraph2_Render Unable to connect L"Wave Parser" to
renderer (80040207)

Then the crash occurs within PullPin_Disconnect because This->pAlloc is NULL.
