STEPS TO REPRODUCE
1. Open a project and let its parsing complete.
2. Type "#include <some header>"
3. KDevelop crashes before I finish typing the complete line, usually at
"#include"
OBSERVED RESULT
A segfault
EXPECTED RESULT
No segfault
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux, Cinnamon DE
KDE Plasma Version:
KDE Frameworks Version: KDE Frameworks 5.115.0
Qt Version: Versio 5.15.13
KDevelop: git version b5ab8f4435a0fac975f31b4409ca4dae66255349
ADDITIONAL INFORMATION
The parsing must complete before the bug can take place, then it
happens every time. Or at least so often that I'm expecting it. KDevelop was
built from git version b5ab8f4435a0fac975f31b4409ca4dae66255349
I perhaps should prevent the stripping of the debug info out from my production
builds... :)
