I am running macOS 10.14 Mojave, Wine built with mingw and the macOS 10.13 SDK.

Needs https://source.winehq.org/patches/data/188214 to work around a different
regression.

This doesn't happen when trying to create a 32bit prefix.

Terminal output:

wine: Unhandled page fault on read access to FFFFFFFFFFFFFFFF at address

00d8:err:winediag:NtCreateFile Too many open files, ulimit -n probably needs to
be increased
