This is probably the same problem as bug 8459 but I no longer seem to be able to respond to other people's bugs so apologies for duplicating but this info may be useful in diagnosing the problem.  

Here's the relevant part of the gdb backtrace from Linux (RH 7.0, Sun JDK 1.3, Tomcat 3.2.1).  Not sure yet if the bug is in PHP/Java code or in zend_hash (since the latter is getting a 0 index into the hashtable).  BTW, this crash doesn't happen if you build the Debug_TS version (or --enable-debug on Ux).

Could you please try a recent version of PHP (either PHP 4.0.6 (RC4) or latest CVS) and check if the problem persists. If it does, please provide a new gdb backtrace. Thanks you.
