Description Luca Beltrame 2012-05-08 08:15:19 UTC
If Pygments is installed, KDevelop will cash when parsing its files. Specifically, in the Python site-packages dir, "pygments/lexers/functional.py". Backtrace is attached.

Reproducible: Always

Steps to Reproduce:
1. Load KDevelop
2. Wait for parsing to reach pygments/lexers/functional.py
Actual Results:  
KDevelop crashes.

Expected Results:  
KDevelop contines parsing.

Git commit bf99fa429234ea7d66a121c6a7313f6e739a312d by Sven Brauch.
Committed on 19/05/2012 at 21:16.
Pushed by brauch into branch 'master'.

Proper fix for the "the python parser has no information about where a node ends" problem.

This adds a visitor which recursively fixes the missing ranges.
Hopefully also fixes
(my tests work)
