Glad to hear that.  Until 13.3 is out, you could use the binaries I
have provided but these have been stripped from most of their build
options to make them portable for the tests: no OpenSSL, no ICU, and
more things missing.

This one is a separate issue, and I don't think I'll be able to look
at that in more details until the commit fest finishes (development of
14 finsihes in two weeks so the activity is high).  Is this something
new to 13 or did you see that in past version as well on your servers?
