I get the correct error


  select type (x=>a%i)
                      1
Error: Selector shall be polymorphic in SELECT TYPE statement at (1)



with both of these versions (on x86_64-linux-gnu):

gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu8)
gcc version 4.9.0 20131009 (experimental) [trunk revision 203329] (GCC)

Yes, also on my other computer with a more recent version (4.8.2 20131003) it
works right. I have more computers and I sometimes loose track of when did I
recompile gcc last time there. I assumed it is from fifth September and it is
actually ninth May.

Great, so I guess we can close this PR as fixed ...
