Testing a release build is crucial, because that's what end users use, and
it's the only way to provoke platform compiler optimization bugs.

Of all the build variations beyond that, --with-pydebug is by far the most
valuable to try.  In the 2.3 line, it's especially valuable to do a debug
build because it triggers new memory management code in Python that can
catch many kinds of insanity (reading/writing out of bounds, reading
uninitialized heap memory, reading heap memory that's already been free()ed,
...) early.

Which build variations beyond that to try may depend on how much resource
the PBF is willing to throw at them.
