Can't find any references using 'semantic-symref-symbol'

I'm getting No references found message whenever I use "semantic-symref-symbol" (C-c , g) trying to get all the references to any symbol, whether the symbol is a C++ class member variable or a local variable, it just couldn't find any reference. The gtag database are under my project root. In my .emacs file I have the following:

(require 'semanticdb-global)
(semanticdb-enable-gnu-global-databases 'c-mode)
(semanticdb-enable-gnu-global-databases 'c++-mode)

When I type "global -xs symbol" under command line, it shows all the reference to the symbol correctly. But why semantic couldn't find anything? On the other hand, 'semantic-symref' works fine on looking for references of a class or class member function, but it doesn't work for variables.

Is it simply a bug, or am I missing anything that keeps symbol reference from working?

This problem is with how GNU Global is used in Semantic came up on the mailing list the other day. GNU Global lets you find occurances of tags (with -r) or random symbols (-s), and Semantic uses the -r flag, and the variables you mention are not considered tags by GNU Global.

In the cedet-global.el support file the function cedet-gnu-global-search, it was proposed to use or add the -s flag when searching for a 'symbol. I don't know what the resolution will be at this time, however.

You can see the whole thread on the cedet-devel mailing list:
