------- Comment #2 from tkoenig at gcc dot gnu dot org 2009-06-22 19:28 -------
Confirmed.
Backtrace:

The problem appears to be an unititialized (?) size when
ncopies is zero in gfc_simplify_spread:
(gdb) up
#1 0x08132738 in gfc_simplify_spread (source=0x8c370b8, dim_expr=0x8c37128,
ncopies_expr=0x8c37198) at ../../../gcc/trunk/gcc/fortran/simplify.c:5121
5121 if (mpz_get_si (size)*ncopies >
gfc_option.flag_max_array_constructor)
(gdb) p size
$1 = {{_mp_alloc = 147026216, _mp_size = 1953392936, _mp_d = 0x736e6972}}
(gdb) p ncopies
$2 = 0
This patchlet avoids the ICE:
ndex: simplify.c

if (source->expr_type == EXPR_CONSTANT)
I'm regression-testing it right now.

------- Comment #3 from dominiq at lps dot ens dot fr 2009-06-22 19:49 -------
I have tested the patch in comments pr40472#12 and pr40472#13 and it fixes the
failures in comment #0 and the failure reported in pr40472#9.

Thomas, I think your patch does not help.
(In reply to comment #2)
> This patchlet avoids the ICE:
> gfc_array_size (source, &size);
> - if (mpz_get_si (size)*ncopies > gfc_option.flag_max_array_constructor)
> + if (ncopies && mpz_get_si (size)*ncopies

You only added a check for ncopies == 0, but for
print *, spread(1,dim=1,ncopies=4)
ncopies > 0 but there is still the problem:
SIZE is never initialized if SOURCE= is a scalar. I think the patch in PR 40472
is the correct one - and is has also been approved by Paul and tested by
Dominique. (Here, it fixes the valgrind error and regtests on x86-64.)
