Got back to this after some time. Seems like KDevelop's CMake parser can't
handle strings with 0 bytes inside. Specifically, creating the CMake console
project from the template and appending contents of
Tests/RunCMake/Syntax/NullTerminatedArgument.cmake file from the CMake project
to the CMakeLists.txt make KDevelop crash on it either during project loading
or upon opening the file.
Valgrind says:
