rtags not indexing the functions fully even for rtags source code.

Describe the bug rtags not indexing the complete function and i can not see the symbol info for a part of function. This leads to various commands not working i.e jump to definition, references, symbol info etc.

To Reproduce Steps to reproduce the behavior:

Index the rtags repo with rc -J
Some part do not work for rc commands given below.

Expected behavior functions should be indexed and all expected symbols should be available.

Screenshots/Backtrace The following piece of code does not index in given function. This is one example from rtags repo itself.

File: src/ClangIndexer.cpp Function: bool ClangIndexer::superclassTemplateMemberFunctionUgleHack(const CXCursor &cursor, CXCursorKind kind, Location location, const CXCursor &/ref/, Symbol **cursorPtr)

        case 1:
            // ### not sure this is correct with line/col
            return handleReference(cursor, kind,
                                   Location(location.fileId(), location.line(), location.column() + 1),
                                   alternatives.front(), cursorPtr);
            break;
        case 0:
            break;
        default:
            warning() << "Can't decide which of these symbols are right for me"
                      << cursor << alternatives
                      << "Need to parse types";
            break;
        }
    }

----> Here cursor on handleReference() do not jump to definition(no commands works like references, symbol info etc) and also no output for rc command (rc --absolute-path -f src/ClangIndexer.cpp:991:24 and similar)

--> dump of file map shows no content for above mentioned code lines. From 987 to 1004, there is no database for any symbols.
