Fixed with r145651 (I messed up the PR number in the ChangeLog entry, though).
Closing.

Reopening. The check for comparing the interfaces was taken out again in
r142520, since there were problems with intrinsics. Details will follow.

Check backed out in PR 38415, cf.
http://gcc.gnu.org/ml/fortran/2008-12/msg00089.html

I'm afraid I'll have to remove the gfc_compare_interfaces check in
 gfc_check_pointer_assign again, since I just noticed that it has lots
 of problems with intrinsics (both in lvalue and rvalue)

patch v1

Here is a draft patch which correctly copies the typespec and formal args for a
PROCEDURE statement with INTRINSIC interface. It also makes
gfc_compare_interfaces work with intrinsics and re-enables the interface check
for procedure pointer assignments.

Stuff like the following should work now:

procedure(iabs),pointer::p1
procedure(f), pointer::p2

! valid
p1 = iabs
p2 = iabs
p1 = f
p2 = f
p2 = p1
p1 = p2

! invalid
p1 = abs
p2 = abs

contains

  integer function f(x)
integer :: x
f = 317
  end function

end
