-- Information about the crash:
I've got a small Meson project with a program I need to debug, and I'm having
some trouble with GDB so I decided to give LLDB a try, but KDev crashed when
starting debugging. Turns out LLDB wasn't installed yet, nor was the MI driver.
I selected LLDB for the debugger in my Launch Configuration and tried to start
debugging. I have selected to run the program in Konsole, and it starts Konsole
then KDevelop crashes leaving an empty Konsole window behind.
I realized I didn't have LLDB installed yet, so I installed it, and the crash
persisted, so then I installed the LLDB MI, and that resolved the crash, so it
seems the crash is due to the selected debugger and interface not being
present. :-)
Note on debugging symbols:
I have Gentoo configured with splitdebug globally so debugging symbols are
present but separate for, well, everything. If the symbols aren't loading
properly and the backtrace is of low quality, I can try to improve it if I get
some guidance on how to make the separate debug symbols load.
The crash can be reproduced every time.
