If you configure xapian-core with --enable-debug --enable-debug-verbose
then you'll turn on all the internal consistency checks and also compile
in code which produces a log of control flow through much of the library.

You can then set XAPIAN_DEBUG_LOG and XAPIAN_DEBUG_FLAGS in the
environment to control what is logged and where.  By default, nothing
is logged.

This is described in the HACKING file in xapian-core, so I won't repeat
all that.  It doesn't explicitly say, but setting XAPIAN_DEBUG_FLAGS=-1
is an easy way to turn on all debug logging.  I'll add a note to that
effect.  Hmm, and it also doesn't say you can put "%%" in
XAPIAN_DEBUG_LOG and it will be replaced with the process-id, which
is sometimes useful.

Cheers,
