Comment:

 I have tracked down the problem and posted a patch for mingw-w64.

 https://sourceforge.net/p/mingw-w64/mailman/message/35935261/

 If they accept the patch, we can add it to our build as well. I have
 confirmed with this patch that no RWX or X/COW pages remain.

 This patch solves at least some of the RWX pages reported in Tor Browser
 for Windows (#22584) as well.
