e7af9751d9 has:

--- a/source/genCases_f32.c
+++ b/source/genCases_f32.c
@@ -411,6 +411,7 @@ static float32_t f32Random( void )
       case 6:
          return f32RandomQInfP3();
       case 7:
+     default:
          return f32RandomQInfPInf();
      }

Why the default is with 7 and not 3 or 5?
Shouldn't we abort() or mark with __builtin_unreachable()?
