KDevelop Crash Report and the code snippet

SUMMARY
I was doing some refactoring, shifting towards compile time routines.
it started crashing when i entered this line:

std::apply([](auto&&... arg) {((Textures[frameID] = textureInterface.GetElement(arg)), ...);}, t);

the parser started in the background, and in the process, it killed the whole IDE.

STEPS TO REPRODUCE
1. Create a CMake C++17 Project
2. Paste the code included in the crash report
3. Wait for the background parser

OBSERVED RESULT
Crash

EXPECTED RESULT
