Description Vishesh Handa 2012-08-05 16:24:59 UTC

Application: kdevelop (4.4.60)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.4.6-1-ARCH x86_64
Distribution: "Arch Linux"

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

I opened up the nepomuk-core project from KDevelop, and it got stuck - The GUI was grey and unresponsive. I had to manually kill kdevelop. This happened twice, at which point KDevelop on starting up asked if I wanted to recreate the cache. I said, yes, since I assumed the cache had gotten corrupted.

KDevelop opened up fine, but about 10 seconds later, it crashed.

I just updated KDevPlatform and KDevelop today.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".

Comment 2 Ivan Shapovalov 2012-08-05 18:31:00 UTC

Crashes in stdlib code (esp. down rbtree's operator--(), which I've personally encountered several times) usually mean binary incompatibility arising from updating toolchain or something similar. Try to fully clean build directories, reconfigure and rebuild both kdevplatform and kdevelop.

I tried a 'make uninstall' and I manually cleaned up all the kdev* files in my ~/kde/ installation. It didn't help, kdevelop still crashed. Now I'm rebuilding it from scratch. Let's see how it goes.

It worked. Closing this bug as INVALID.
