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

Starting from a new C++ Terminal (Hello World) project, added --std=c++17 to CXXFLAGS.
Set breakpoint on first line in main(), then Debug the program.
Using GDB window, execute "watch $rsp", then continue execution => execution gets interrupted on this breakpoint.
Add new breakpoint of type "Write", but don't fill in condition, press ESC.
Delete this new breakpoint => crash

Tried to reproduce, but didn't crash anymore.

The crash does not seem to be reproducible.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
