As reported in comment#6, this cleared itself.

This seems to have fixed itself - all three testcases run fine on  4.3.0
20070525.  I'll check it out tonight on x86_ia64 and, if all is well, I'll
clear the PR.

RESHAPE is not simplified, because "x" has type EXPR_CONSTANT (scalar constant)
which is not accepted by the simplification routine gfc_simplify_reshape,
because it wants arguments to be EXPR_ARRAY (ie array constructor). Thus, the
following code fails to compile:
  integer, parameter :: x(1) = 1, y(1) = reshape(x,(/1/))
  print *, y
  end
while that other one works fine:
  integer, parameter :: x(1) = (/1/), y(1) = reshape(x,(/1/))
  print *, y
  end

I don't know if it's OK for x to have type EXPR_CONSTANT, but I think it is. In
that case, gfc_simplify_reshape should be modified to account for this
possibility.

The ice is happening here:

/* Create an array constructor from an initialization expression.
   We assume the frontend already did any expansions and conversions.  */

tree
gfc_conv_array_initializer (tree type, gfc_expr * expr)
{
  gfc_constructor *c;
  tree tmp;
  mpz_t maxval;
  gfc_se se;
  HOST_WIDE_INT hi;
  unsigned HOST_WIDE_INT lo;
  tree index, range;
  VEC(constructor_elt,gc) *v = NULL;
gfc_show_expr (expr);
  switch (expr->expr_type)
{
case EXPR_CONSTANT:
case EXPR_STRUCTURE:

The comment indicates that the initialization expression should already be
expanded.  For the test case given, expr->expr_type is FUNCTION for which there
is no case.  The function needs to be evaluated before getting here.

Reduced testcase:
 real, dimension(1), parameter :: r=1.0
 real, dimension(1) :: s=RESHAPE(r,(/1/))

 IF (ANY(s.NE.1.0)) CALL ABORT()
 END

The following code repeats the ICE:

 character(LEN=2), parameter :: a="a "
 real, dimension(2,2), parameter :: r=1.0
 character(LEN=4) :: b=REPEAT(a,2)
 real, dimension(4) :: l=RESHAPE(r,(/4/))
 character(LEN=3) :: c=TRIM("a ")

 IF (b.NE."a a ") CALL ABORT()
 IF (ANY(l.NE.1.0)) CALL ABORT()
 IF (c.NE."a  ") CALL ABORT()
 END

This is thus not something coming from the lack of transfer constant-folding.
