ORA-00600: internal error code, arguments: [kghstack_free1], [kkqvtSyncOptBinds: srcbindpp], [], [], [], [], [], [], [], [], [], []

Environment 12.1.0.2
Got this issue after changing CURSOR_SHARING parameter to FORCE from EXACT.

It listed for a specific reporting query .

Issue fixed by specifying
/*+ CURSOR_SHARING_EXACT */ hint on the problem statement.

Other oracle suggestion you can see Doc ID 2126243.1
