ORA-00600:[kkbrcupfind2] while dropping a column -> Doc ID 1487527.1 not working

Hey guys,

we are having a serious issue on one of our dev db - oracle 11.2.0.1 (i know, i know .. it will be upgraded in next few months).

Oracle threw away ora-0600 ORA-00600:[kkbrcupfind2] with no additional parameters.

I found a doc ID 1487527.1  but it's not working.

When I try to set column as unused it throws an error ora-12986 columns in partially dropped state. Submit ALTER TABLE DROP COLUMNS CONTINUE.

Executing ALTER TABLE DROP COLUMNS CONTINUE ends with ora-0600 ORA-00600:[kkbrcupfind2].

So i gave a try to:

- rebuild an functional index correlated with this column

- drop this column in a few ways
