Help with corrupted defines [bug 11990]

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?
