I'm not surprised to see a problem in anything with two 0's. It's
the first release ever with tree-ssa. It was inevitable that users
would find problems, and I certainly wouldn't use 4.0.0 for production
(distros that use it will of course add patches, including the one
for PR 21173).

We always knew we needed 4.0.1. The problem, though, with a very quick
release to fix this one is that we could discover a second nasty one.
If this bug is as bad as you say, it's probably worth putting out 4.0.1
faster than Mark originally planned. But tomorrow is too soon.
Also, we can point people to a patch for this PR so that they can get
further in their testing.
