Description Alexander 2013-03-18 15:20:27 UTC 
Hello,
I'm using KDevelop git master (2013-03-18).

I've been experiencing these crashes recently, they seem to be easy to reproduce. Happened with gdb 7.5.1 and now with a recent snapshot as well.

Reproducible: Always

Steps to Reproduce:
1. Compile some project, click the "Debug current launch" button.
2. Add some breakpoint, make the execution stop at that breakpoint.
3. Click the "Stop all currently running jobs" button.
And KDevelop crashes.
Actual Results:  
A crash.

Expected Results:  
No crash.

openSUSE 12.2 x86-64, with some updated packages.
kdelibs4-4.10.1-545.1.x86_64
libqt4-4.8.4-305.1.x86_64
gcc-4.7-2.1.1.x86_64
gdb-7.5.50.20130215-88.1.x86_64
glibc-2.15-22.17.1.x86_64

Comment 2 Aleix Pol 2013-04-03 23:54:20 UTC 
this backtrace doesn't have enough information and I haven't reproduced this bug.
Please re-open if you find more information for us to fix this.
Comment 3 Alexander 2013-04-05 16:18:29 UTC 
Hello,

I just compiled the current git master in RelWithDebInfo and got the same crash. It seems that the crash is project-dependent. For example, I can reliably crash KDevelop with one of my Qt projects (not open source, unfortunately), when my program's window is open, but not when the window has not been created yet. I tried the same with my other project and couldn't get the crash.

I'm pasting the backtrace below, but I'm not sure if it's informative.
If not, is there any way to get a useful crash log?
