Description Andreas Pakulat 2012-01-22 09:18:49 UTC

Application: kdevelop (4.3.60)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.1.0-1-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

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

This occurs every time I try to write the case-label in a switch statement here and IIRC didn't
happen yet with master from a week ago (I do have an existing switch further above written
back then). Its just simple text-typing no code-completion etc. involved.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted

Comment 1 Andreas Pakulat 2012-01-22 09:21:16 UTC

Just tried, this also happens when no background parser is running (so the cmake-parsing in the above backtrace is irrelevant) and I can reproduce this with the older existing switch too when adding a new case-label there.

Comment 2 Andreas Pakulat 2012-01-22 09:26:16 UTC

Also tried with other projects (kdev-custom-buildsystem, kdevplatform itself) and everywhere typing letters for a case-label will crash kdev.

This is the backtrace when no background parser is running:

Comment 3 Milian Wolff 2012-01-22 13:53:27 UTC

are you sure you are up2date?

I thought I have fixed that with commit ec88f4a54b41e9676ed5ad020f4598293512a3ed ...

*** This bug has been marked as a duplicate of bug 291468 ***

Comment 4 Andreas Pakulat 2012-01-22 16:38:25 UTC

Actually after reading the dupe, this is not a duplicate. Thats also matched by still reproducing the bug.

So just to make the difference clearer: I'm having an int-variable that I switch on and the case-labels are using defines. I'm not completing the defines either, just starting to type their names.

So something like this crashes for me:

#define SUCCESS 0
#define ERROR 1

int foo = 0;
switch(foo) {
case S|


For normal enum-variables everything is fine for me too, hence re-opening this report.
