Summary: KDevelop blocks randomly
Product: kdevelop
Version: 4.2.60
Platform: Compiled Sources
OS/Version: Linux
Status: NEW
Severity: normal
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: iamsergio@gmail.com
Version: 4.2.60 (using Devel)
OS: Linux
Sometimes when I'm coding, KDevelop freezes and I have to kill it.
I'm using kdevelop and kdevplatform from master, kdelibs from 4.7.
Is there any other module that I should update?
Here's the backtrace:

(gdb) quit
Reproducible: Always
Steps to Reproduce:
Only happens with editing some pieces of code.
Right now, I had "int result = -1", and edited it to "int result ++mLatestChangeId"
I retried, and notice it only happens after I press *save*.
So, editing is ok, unless I save the document.
Expected Results:
No freeze.
