Attachments: File that I was editing when problem occured

Description Philippe 2015-01-17 09:45:16 UTC 
Created attachment 90467 [details]
File that I was editing when problem occured

Application: kdevelop (4.6.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-44-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
While editing source code, I wanted to cancel a operation. Source code file is in C++(11) and is a test using QTestLib.

Step 1: (editing code..)
............. (many lines of code, >3000)
QVERIFY(expressionA);
QVERIFY(expressionB);
.............. (other lines of code)

Step 2: (comment a block)
............. (many lines of code, >3000)
/*
QVERIFY(expressionA);
QVERIFY(expressionB);
*/
.............. (other lines of code)

Step 3: Cancel operation (Ctrl+z key).
At this state, nothing happens and KDevelop becomes "less responsive".
After 3 seconds, I close it, then, after 2 seconds, I start it again: here, crash was detected and report dialog opens.

The problem is, I do such cancellation many time in a day, and such problem is very rare.

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

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!

Dear Andrew,

I'm currently using Kdevelop 4.7.3, and I never had this problem with it.

Kind regards
Philippe
