Version: 3.2.91 (using KDE 3.4.91 (beta1, >= 20050910), Gentoo) Compiler: gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8) OS: Linux (i686) release 2.6.12-gentoo-r6 I'm using Kdevelop for PHP. I've got "Enable realtime parser" turned off (Bug 113690). I've got "Enable code completion" and "Enable code hinting" turned off, because one of those makes the editor unusably slow. If I now press Ctrl+Space, Kdevelop crashes. Every time. Backtrace: Using host libthread_db library "/lib/libthread_db.so.1". `system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

I can confirm this using current 3.5 branch (rev. 467250)

I can't reproduce this bug in 3.4, if somebody can please re-open.
Nice, just after closing it I managed to crash kdevelop. Re-opening. What I did was disabling the code-completion/hinting and also the realtime-parser. Then go to a member function of a class and type return $this-><ctrl+space>. Backtrace is the same is in the original report.
