welp, maybe someone smarter than me can chime in here. Seems like we're failing
to properly allocate the string that gets set. I really don't know how to fix
this. You can achieve this log with WINEDEBUG=trace+msxml,+pid,+tid with the
previously attached patch applied.

Here's the relevant bit from the log:
