Bug ID: 67277
Summary: segfault when passing a missing optional argument to
an elemental intrinsic
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

test case
The testcase is the intrinsic variant of generic_31.f90 from pr66929.
It leads to a null pointer dereference at runtime when trying to evaluate
the absent optional argument.
The problem is the same as pr66929, we don't have a procedure interface symbol
for the call, so we don't know that the dummy argument of the intrinsic
procedure is optional, and thus assume that it is always present.
