Using a custom compiler in a kit breaks static code analysis

1. Setup a sample project with an external build system (I use SCons). The static analysis works correctly.

2. Define a custom compiler. I'd like it to be similar to Microsoft Visual Studio 2015 (MSVC), but with "Custom Parser Settings..." (I want to use a custom compiler option because I need to customize the parser settings). Note that I put the header files of the standard library in the custom compiler settings. Am I doing something wrong?

3. Specify it as the C++ compiler (Options->Kits->Manual->Desktop(default)->Compiler C++)

4. The static code analysis no longer detects the constructs from the standard library.
