Confirmed, reduced testcase:
void CheckFile ()
{
     char tagname[10]; char * a = tagname;
      int validate()
      {
        return (a == tagname+4);
      }
      if(a == tagname)
        validate();
}

t.c: In function ‘CheckFile’:
t.c:11: error: Invalid operand to binary operator
FRAME.1D.1246.aD.1249;

t.c:11: internal compiler error: verify_stmts failed.
