Compile debug causes package to become invalid

Question

We're running 10.2.0.4.0 and I have a large package (7730 lines) which compiles fine on it's own. However, if I try to enable debug mode, I get an error:
SQL> alter package mypkg compile debug package;
Warning: Package altered with compilation errors.
SQL> show errors;
No errors.
If I perform another alter command without the debug parameter, then it compiles fine:
SQL> alter package mypkg compile package;
Package altered.
Also, if I compile this package using the "Compile for Debug" button in SQL Developer then I actually get an error message:
Error(1): PLS-00707: unsupported construct or internal error [2603]
Does anyone have any idea what's going on here? I've spent the past couple days searching for a solution and while I've seen many cases of people having the PLS-00707 error, I wasn't able to find anyone who only receives it when compiling for debug.
