 Hi,
 
 here's a cleaned-up testcase that just ICEs - no warning:
 
 ------------------------------snip here-------------------------------
 void foo (double d)
 {
     union { double d; int i; } u;
 
     while (1)
     {
         u.d = d;
         if (u.i & 1) return;
     }
 }
 ------------------------------snip here-------------------------------
 
 BTW, if you add a semicolon after "ret:" in the original testcase, the
 warning also vanishes.
 
 Regards,
 Volker
