Well ... take a guess where to look :-P

If you are disabling anything via manual alteration of the code
instead of the ./configure --disable options (you mention using sed)
then one of the things you *do* need is the debugs() logging.

cache.log / debugs() is not just for debugging either. It is also for
recording major/critical events that you as administrator really,
really need to be made aware of.



Though, on the diagnosis I suggest at least trying with a macro name
other than "NODEBUG". For some reason that macro is used to disable
the assertion handling.
