RDBMS 9.2.0.3 PLSQL version 5.1.3.704

I have been working with PLSQL Developer for awhile and everything has been fine.

Suddenly I am having the following problems.

1. When compiling I get an EOF on Communication channel. I saw this issue in a seperate thread and the work around works, but I don't agree that this is an RDBMS bug. Bouncing the DB does not fix.

2. The Debugger hangs when a breakpoint is hit. I get the following errors reported:

ORA-00600: internal error code, arguments: [15419], [severe error during PL/SQL execution], [], [], [], [], [], []

ORA-06544: PL/SQL: internal error, arguments: [2603], [], [], [], [], [], [], []

ORA-06553: PLS-707: unsupported construct or internal error [2603]

The debugger is the primary tool that I use and is currently non operational.
