I posted a patch for this on the PR in August 2010. Dominique pointed out that it caused repeated error messages in some testcases; eg. arithmetic_overflow_1.f90
As it happens, that seems to have crept in at some time even without
the patch for this PR. Nevertheless, I have modified the patch
slightly to prevent any more escalation. Apart from this, the patch is
very straightforward.
Bootstraps and regtests on FC28/x86_64 - OK for trunk and....?

* expr.c : Add a prototype for scalarize_intrinsic_call.
(gfc_simplify_expr): Use scalarize_intrinsic_call for elemental
intrinsic function calls.
(scalarize_intrinsic_call): Add 'init_flag' argument. Check if
the expression or any of the actual argument expressions are
NULL. Before calling gfc_check_init_expr, check 'init_flag'.
Only simplify the scalarized expressions if there are no errors
on the stack.
(gfc_check_init_expr): Set 'init_flag' true in the call to
scalarize_intrinsic_call.
