Try and see which of the "tools" semantic-symref-perform-search ends up 
using.

If you have an index generated by Global, idutils or CScope, it could be 
missing this symbol and have the search fail because of that.

Otherwise the search falls back to Grep, see 
lisp/cedet/semantic/symref/grep.el. You can edebug it there.
