ORA-600 [26599] creating java BLOB class

I'm trying to install a 3rd party product in an Oracle database running on HP-UX 11. We were running 9.2.0.4 and I encountered this error:

ORA-07445: exception encountered: core dump [ph2opf_pattern_formals()+1408]
[SIGSEGV] [unknown code] [0x800003FA40100000] [] [] Current SQL statement
for this session:
create or replace package body export_object wrapped

This appeared to be fixed by patch 3065127 (Metalink note 241160.1) but the note said it was also corrected in 9.2.0.5, so we just upgraded the database (to 9.2.0.6). We dropped the user & tablespace, recreated them, and then tried to re-install the 3rd party package, but now we get this error:

ORA-00600: internal error code, arguments: [26599], [1], [249], [], [], [],
[],[] Current SQL statement for this session:
create or replace java class using blob class from rws_java_class$

I'm not able to find anything via Metalink or Google. We've opened a TAR with Oracle & an equivalent ticket with the application vendor but don't seem to be getting anywhere fast. I thought I'd ping the list to see if anyone else may have seen this before...

Thanks!
