Compiling the following code (extracted from
http://mathalacarte.com/hpcconsult):

  INTEGER, PARAMETER :: ISCLASS(1) = &
    (/&
    Z'FF800000'& ! IEEE_NEGATIVE_INF
    /)
    print *, isclass
end

gives the following ICE

isclass_3.f90: In function 'MAIN__':
isclass_3.f90:5:0: internal compiler error: in gfc_conv_array_initializer, at
fortran/trans-array.c:5473
     print *, isclass

while it compiles with -fno-range-check.
