Hi.

I wanted to call attention to
https://bugzilla.mozilla.org/show_bug.cgi?id=1322554 (Startup crashes in
BaseThreadInitThunk since 2016-12-03) -- a startup crash resulting from DLL
injection early in the process -- which was resolved fixed for 32bit
Windows on 5/24.

This particular fix[0] has the potential side effect of solving other bugs
as well, ones that may have very different signatures that deal with
remotely-injected code[1].

Just a caution that it's not going to impact all injection issues. We know
that there is an as-yet-unidentified increase and decrease in this crash
prior to patch landing[2]. Carl Corcoran, who landed this, will be looking
at that time period as well to attempt to find contributing causes (any
help diagnosing is probably welcome, though I defer to ccorcoran).

Also, just a shout out that this was Carl's first patch.

Thanks!
