Seg fault on optional pointer argument

[Berggren__Bo]

Using a pointer to an integer array as an optional argument cause a segmentation fault (ifort 18.0.3.222 Build 20180410, CentOS 7.5).

See attached code for an example.

$> ifort -c opt_args.f90 
$> ifort -o test_opt_args test_opt_args.f90 opt_args.o
$> ./test_opt_args 
 get_vals(x, y, p)
   x:            1
   y:            2
   p:            1           2           3           4

Confirmed, this works with gfortran 5 and 9, and with nagfor 6.2 and pgfortran 18.5. And it works with ifort v17, so this is a regression in v18 and v19beta. Could you submit a bug report via the support center?

I cannot submit a ticket even though I have a valid license. There must be something wrong with my account.

Can you submit it for me?

I would but off for summer vacation now. Not in front of a computer. Maybe the Intel stuff picks it up...
