Status
======

We are in Stage 3 and the trunk is open for regression and documentation
fixes only.  When we reach zero open P1 regressions, we will create a
release candidate for 4.3.0, branch and announce the opening of Stage 1
for 4.4.

This causes the build to fail like so:

make profiledbootstrap is still broken on (some?) 64bit targets when BOOT_CFLAGS="-O2". We're seeing this on x86_64 and ppc64. During the third stage something goes wrong in the preprocessor: I understand that this may not be a showstopper, but I wanted to be sure you're aware of it. This is PR #33992, which is still unconfirmed. I think this is because it was originally filed using a Gentoo GCC, but we've since confirmed it with several vanilla 4.3 snapshots.
