We've now run with --enable-pool-debug... and got no errors at all! That server
has been running for over four days without a single abnormal exit. Meanwhile we
set another server up without pool debugging - but otherwise an identical
configuration and set of modules - and that contiues to have bus errors and seg
faults (a few a day).

So it would seem that something in the debugging code is either catching the
problem, or making it go away. At a quick glance, it would appear the debug code
abort()s when it sees a problem - which we haven't seen... so I don't think
that's happening. In which case it's either doing something correct where the
non-debugging code goes wrong, or it's changing the program behaviour in such a
way that the error conditions don't arise.

I'm going to have a look at how pool initialisation/destruction differs between
the debugging and non-debugging code paths, but if you've got any insights of
what to try or to look into, it would be much appreciated.
