Summary: KDevelop Crash in PHP Parser
Product: kdevelop
Version: 4.2.60
Platform: Compiled Sources
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: grundleborg@googlemail.com
Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.41 (4.7 >= 20110106) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
Working on a PHP project in KDevelop. I had just typed the following code \
into a file:
<?php
if (isset($uri_bits[3])) {
At which point KDevelop crashed, and then crashed almost immediately on \
each subsequent restart of it (even after clearing out duchain data).
I'm not sure if the same crash would happen out of context of the rest of \
the project however.
Version used is latest git from 30th March (of entire KDE trunk, including
kdevplatform, kdevelop and kdev php plugin).
The crash can be reproduced every time.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
