This didn't work.  All of the g++ command lines had “-O3 -march=i686”
and none of them had “-O2 -g”.

It worked when I replaced “make” by “make CXXFLAGS="-O2 -g"”.

New “bt full” output below.  “ConfigVector<BuildingType>::get ()” is
no longer listed as a separate stack frame.  It looks like it got
inlined.

I'm afraid you'll have to wait on this.  I've spent too much time on
glob2 already!  I think I've used up my entertainment time budget for
the next several months already.  :-(

Um, I have listed a _lot_ of issues.  Perhaps you could indicate which
precise ones are worth separate bug reports.

Okay, good.

Have you reproduced it?

Yes, I'm getting this same crash too.

Hmm.  I haven't yet retried with 0.8.21 the saved game that failed
with 0.8.22.
