This is in update to bug #383 -- I cannot compile PHP after
compiling Apache, but this appears to be an Apache problem.
I downloaded Apache 1.3b7 and PHP 3RC5 and the system
appears to run mostly with fopen wrappers enabled.
However, it still dumps core in some situations.  Here is
the end portion of a truss:

This bug has gone away - probably not PHP-related to begin with.
