failure to find reference to variable in lambda capture

[Jacob-Burckhardt]

Observed behavior

It fails to find references to the variable "i".

int main() {
   int i=0; // line 2
   return [captureVar=i](){ return captureVar; }(); // line 3
}

Expected behavior

It should have found the reference to "i" on line 3.

Steps to reproduce

1. Put the cursor on "i" on line 2.
2. In emacs, run M-x xref-find-references.
