cppcheck-gui crash when importing compile_commands.json

[wy163]

Hi, this issue is 100% reproduced on my side. I am not sure if I did something wrong, as the steps are quite simple. The error message is as below.

looking for library '/home/w/Desktop/tmp/sample/cppcheck/std.cfg'
looking for library '/home/w/work/apptest/app/main_project/cppcheck_git_ssh10/cppcheck/build/bin/std.cfg'
looking for library '/home/w/work/apptest/app/main_project/cppcheck_git_ssh10/cppcheck/build/bin/cfg/std.cfg'
Checking project file "/home/w/Desktop/tmp/sample/cppcheck/helloworld.cppcheck"
Checking file "/home/w/Desktop/tmp/sample/main.cpp"
cppcheck-gui: /home/w/work/apptest/app/main_project/cppcheck_git_ssh10/cppcheck/lib/preprocessor.cpp:72: Preprocessor::Preprocessor(const Settings&, ErrorLogger&, Standards::Language): Assertion `mLang != Standards::Language::None' failed.
Aborted (core dumped)

Steps:

make a folder named sample containing the files to be checked
make a subfolder named cppcheck to save the helloworld.cppcheck
make build dir named build under sample for cmake and let cmake to generate a compile_commands.json
launch cppcheck-gui, create a new project, and import the compile_commands.json

I uploaded the sample.zip. Could you pls help take a look? Thanks!

Known issue tracked in https://trac.cppcheck.net/ticket/13909.

Since the prerequisites have been merged I hope to finish https://github.com/danmar/cppcheck/pull/7570 later today, so it will hopefully be merged over the weekend.
