A recent gfortran ICEs on the following code:

INTEGER :: I
CHARACTER(LEN=100) :: data="1.0 3.0"
REAL :: C,D
READ(data,*) C,D
I=TRANSFER(C/D,I)
SELECT CASE(I)
CASE (TRANSFER(1.0/3.0,1))
CASE DEFAULT
 CALL ABORT()
END SELECT
END

------- Comment #1 from fxcoudert at gcc dot gnu dot org  2007-03-16 19:50 -------
Reduced testcase follows:

$ cat a.f90 
  integer :: i
  select case(i)
  case (transfer(1,1))
  end select
  end
$ gfortran -c a.f90 
a.f90: In function ‘MAIN__’:
a.f90:1: internal compiler error: in gfc_conv_constant_to_tree, at
fortran/trans-const.c:278

This is another TRANSFER constant-folding bug, they should probably be fixed by
the same function. Brooks said he was looking into it.
