Summary: When editing function definiton's header line,
KDevelop crashes, always
Product: kdevelop
Version: unspecified
Platform: Unlisted Binaries
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: msoos@freemail.hu
Application that crashed: kdevelop
Version of the application: 3.9.96 (using KDevPlatform 0.9.96)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-2-amd64 x86_64
Distribution: Debian GNU/Linux 5.0.3 (lenny)
What I was doing when the application crashed:
I edited the function definition (in the .cpp file):
uint Gaussian::eliminate(matrixset& m, uint& conflict_row)
{
...
}
(note: function was declared in a separate, .h file)
to something like
uint Gaussian::eliminate(matrixset& m, uint& conflict_row, uint&)
{
...
}
I never actually managed to write anything after "uint&", since kdevelop
crashed. I can do this with any function definition in my program. It is so
reproducabe, that I actually edit all my func. definition's headers in
vim/emacs, as kdevelop _always_ crashes... If you need any more of these
tracebacks, just contact me, I can provide any number of them.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
The current source language is "auto; currently c".
