I have problems like this on a regular basis in big/complex (well by my standards anyway)
codebases that have heavy php5 oo in them. no errors _anywhere_ if I have a parse error
or a require_once statement fails, I havbe had the problem since php5beta3 (when I
started using php5) and have seen it happen on every version of php5 upto 5.0.4 (the highest version
I have used properly) on windows, debian, redhat and gentoo using apache and apache2.

basically AFAIC there is something wrong _deep_ in the engine but given that I have
no idea how to prove this or provide any kind of short reproduce script I'm left to live
with it ... it may of course be a problem with my code, I'm thinking a possible
reference related segfault issue (and/or maybe __autoload() related). Actually IIRC
Derick Rethans has posted before about issues he has had where problems were not easily
(or at all) reproducable in a short script. (excuses to Derick if I misquote/misremember
what he wrote in the past)

actually this is one of the main reasons I read internals@  - in the hope
someone might offer information that will help me either fix this issue in my code,
expose a real engine problem or possibly give some inspiration as to how to track down
the problem.

... I just wish I had the skills to work this problem :-)

seeing as I don't I live with it and whenever I am faced with a blank page I know
exactly what to do ...  find the parse error and if there is none check every require
statement in the files I have just changed... a process that alweays starts with this one liner:

find . -name \*.php \! -exec php -l {} \;
