Hello,

I noticed that the extension doesn't seem to notice all the errors and warnings in the code. For example, when writing this:

char **a;

a = "string";

It doesn't return any warning or error. Other than that, it seems to work fine.

I'm using compile_commands.json with the -Wall -Werror -Wextra flags enabled, and generated from cmake.

Thank you very much in advance.

Thanks for reporting this. The issue has already been fixed for our pending 0.21.0-insiders release next week. I assume you're using C++ though (C should not give an error in your case)...well, if you expect a compiler warning in C, then that may be fixed after we add warning support (#828 ).

Thank you very much for your quick response.

I was using C in fact.

Thank you for this great extension.

Yeah, even with the "hidden" warnings enabled our parser doesn't show a warning for C files, so this will only be fixed for C++ in our next release.

UPDATE:

Should be fixed (for C++, not C) with 0.21.0-insiders (auto installed if "C_Cpp.updateChannel": "Insiders" is set, or the offline vsix). Let us know if you find any problems with it.
