clang::Parser::ParseOptionalCXXScopeSpecifier(clang::CXXScopeSpec&,
clang::ParsedType, bool, bool, bool*, bool, clang::IdentifierInfo**, bool,
bool): Assertion `getLangOpts().CPlusPlus && "Call sites of this function
should be guarded by checking for C++"' failed.
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
