Application: kdevelop (4.6.90)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.5.0-42-generic x86_64
Distribution: Ubuntu 12.04.4 LTS

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

My project was being parsed ~30% done and I was reading the code and jumping through the source file using the "go to impl" functionality.

Project is a custom Makefile for a semi large project.

Kdevelop and Kdevplatform were compiled from source of the 1.7/4.7 tags.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
