I have been working integrating PHP with Java 2 SE (1.3.1).  I have found that if a "complex" object is returned by another Java method call (as in a static Java method), the php code will core dump.  The problem appears to be related to the zend hashing code.  When the 'new' function is invoked on a Java object, it is hashed by zend for de-referencing.  However, if a java object is returned, no entry is made in the hash for that object, dereferencing said object causes zend to core.

Here's the GDB trace:

Program received signal SIGSEGV, Segmentation fault.
