Semantic result is wrong for C++ function declaration with override attribute

[fperies]

Hello,

I've opened the same issue in Spacemacs project but I've been redirected to Rtags project. Here are the details:

Description
Semantic result is wrong for C++ function declaration with override attribute
It reports a variable definition with override as variable name instead of a function declaration !

Reproduction guide 🐞
Start Emacs
Open a C++ header file with function declarations with override attribute
Invoke command helm-jump-in-buffer
Observed behaviour: 👀 💔
It reports the following:
Variables : int override

Expected behaviour: ❤️ 😄
It should report something like:
Functions: functionName() [override]
