-- Information about the crash:
Editing a function, and double clicked on a variable name in a declaration. Tool-tip popped-up asking if I wanted to rename the usage of the variable. Pressed "alt-1" to perform rename. Then crash.

On restart, recovered the session, and found the renames had completed, so the recovered file contained the results of the rename.

Have seen this several times specifically with this sequence.

The crash can be reproduced sometimes.

-- Backtrace:
