C headers with extern "C" doesn't parse correctly with clang-backend and GCC

    XMLWordPrintable

    Details

      Description

      When GCC is selected as the compiler, the code

      #ifdef __cplusplus
      extern "C"
      {
      #endif
      

      will cause a parser error in clang-backend, causing semantic highlighting for the header to completely fail. (i.e. only preprocessor, comments, and primitives are highlighted, not user types, functions, etc.) If the compiler is switched to Clang the backend works correctly. In case it's version dependent, I'm running GCC 8.2. It appears to detect that it's C code for the header, but thinks that __cplusplus is defined.

      Error encountered with GCC:

       

      Works properly with Clang:

       

      I'm using CMake to generate the project.
