Hey all.  I haven't seen any further traffic on this issue (aside from
myself, that is :-) ).  At one point yesterday, we were seeing an
approximate 5% failure rate; 5% of pages served had errors due to garbage
for a define.

I spent some time poking about the PHP and Zend source yesterday and was
able to call a php_printf() whenever a constant was defined as a string.
Yeah, big deal, I know, but I'm thinking of using that method to verify
that what's going into the hash table is what I've put in the script.

Is there a way to dump an arbitrary Zend hash table from a PHP script?

I've tried stepping through the entire execution of a PHP script with GDB.
Not a pretty thing, as I'm sure most of you know.  I'm not able to
determine even where the line
        define("FOO", "bar");
is read from the file.

Somewhere, the data for the defined constant is getting corrupted.  I
don't know enough about the Zend internals to checkpoint the data at
various points to see if it matches what I expect.  The other problem is
that I can't reliably reproduce the error with a compact script or series
of scripts, which is a major bummer for all involved.

Would someone with the knowledge of the internals of PHP and Zend be
willing to spend some time one-on-one with me any my team trying to get a
solution to this?
