Backtrace from running kdevelop from inside of gdb
***
Immediately after typing "std::array" at the beginning of a (not otherwise
empty) line, kdevelop crashes with a segmentation fault.
Dr. Konqi is unable to produce a backtrace of the crash for some reason as
described here:
https://discuss.kde.org/t/dr-konqi-cannot-load-a-backtrace-after-kdevelop-crashes/43991
but I ran kdevelop from within gdb to get a backtrace anyway.
***
SUMMARY
STEPS TO REPRODUCE
1. Have a very short test C++ project with a main.cpp that #includes <array>
2. Have a line in there reading "uint32_t random_bytes_buffer[buffer_size];"
3. Try to change the C style array to a C++ style std::array<uint32_t, 4>,
beginning by deleting the "uint32_t" keyword and replacing it with
"std::array".
OBSERVED RESULT
Kdevelop crashes.
EXPECTED RESULT
Kdevelop should not crash.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma:
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1
LLVM: 21.1.8
ADDITIONAL INFORMATION
Note: The crash seems to happen deep inside of LLVM code. It may actually be a
bug in LLVM instead of kdevelop itself.
