Any chance the people who know how to do releases might consider a point release with at least this regression fixed:

It's causing my CI situation hell, build machines locking up all over; I don't really want to deploy custom built compilers to the CI machines, that adds a lot of management complexity, but that bug causes me problems all over and I have to keep manually killing hung build jobs.

The bug never made it to LDC, so it's just a DMD issue - all platforms.

It's resolved in the DMD nightly.
