Looking at the source of SPREAD, I note that it does not assert the rank of the
output matrix. Thus, in the fragment from the LLNL test it should be possible
to output the calls to SPREAD to temporary arra

This looks very much like a front end bug. The
"along" parameter gets the wrong value.
Look at this:
$ cat test_spread.f90
program test_spread
implicit none
integer, parameter :: N = 1000

It should be noted that reshape also suffers from the same disorder. To my
mind, this makes the PR rather high priority - after all, the vectorized
functions are among the features

Yet another SPREAD problem:
! Original bug-report by Walt Brainerd, The Fortran Company
integer,dimension(2) :: mi1 = 1
integer,dimension(1,1) :: s
s = spread(mi1,1,2)
end
I agree those intrinsic

The program test_spread from the original bug report
is bogus. dim=1000 doesn't make sense (which invalidates
my comment #5 and makes this particular case a diagnostics
issue).

Can anybody point me to the actual source of the
benchmark that exposed the failure? From the
description, I can't see what's wrong.

Proposed fix for PR 18495.
This appears to fix the benchmark in question.

I believe that reshape needs the same/similar fix.

ret->data = NULL is what the front end generates when
it doesn't know enough

There's something rotten in the state of Denmark.
I've slightly modified Paul's test program with my patch, and
this is what I got:
program test_spread
implicit none
integer, parameter :: N = 100

Spread putting its result into temporary
arrays does indeed do something strange, even if
the front end is providing the space. This is with
an unpatched spread_generic.c:
program test_spread

Looking at the code it seems to me that the return array isn't allocated
anywhere. I don't know the scalarizer well enough, though.

I think I know now how the return array is allocated. This is not the error.
An additional error seems to be that a scalar source is not special cased, as
for PACK, see PR17283:
