-- Information about the crash:
- What I was doing when the application crashed:

The crash is reproducable and happens whenever I click on a member function of a class and select "show definition". The code used here is the one in http://github.com/mgottschlag/CoreRender (master).

The crash can be reproduced some of the time.

-- Backtrace:
