--- Comment #13 from john.harper at vuw dot ac.nz ---
ICE from using MERGE in a constant specification expression, not in this
program an initialization expression because it's an array bound, with gfortran
4.7.2. 
I have tried to install later versions but without success so far. 

cayley[~/Jfh] % cat testmerge3.f90
program testmerge3
  implicit none
  integer,parameter::iarray(merge(2,3,.true.)) = 1, i = size(iarray)
  print "(A,99I2)",'i,iarray =',i,iarray
end program testmerge3
