No problem at all -- always happy to help people who are willing to play
with this hairy stuff -- but please use a public list next time.

You're not alone:
so yes, reverting that commit is your best bet until we have sorted out
what's going wrong there.

Hmm, I'll have to look at that in more detail when I'm back next week.

With the TLS errno patch reverted?  That's unexpected.  Is gdb able to
tell anything interesting?

No, that needs to be updated.  Debian currently is more advanced than my
setup is, so you'll have to look up what they are doing.  People should
be able to point you to the right places.  (I have to leave; back mid of
next week.)
