Bug ID: 100961
Summary: Intrinsic function as value to a class(*) assumed rank
argument fails
Product: gcc
Version: 11.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: mscfd at gmx dot net
Target Milestone: ---
Created attachment 50961
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50961&action=edit
test case
Providing the value of an intrinsic function to a subroutine with an class(*)
assumed rank argument fails. The correct rank is not recognised.
Encapsulating the intrinsic function invocation in parenthesis avoids the bug.

AFAIU the test it works for me with GCC10, 11, and 12.
What is tour output of
Fortran -v?

second test case which segfaults
Playing around with some variants in select_rank_expression2.f90, I can see
that I sometimes get correct results, sometimes the rank is correctly
recognised, but not the type, and (as is the case for attachment
select_rank_expression2.f90) it even can segfault with an invalid memory
access. I get all these behaviours by selecting different sets of the four
"call p(..)" lines and varying the order in which they are executed.

In contrast to gfortran-11, with current master I do not see any errors or
segfaults (not even with valgrind) anymore. Seems to have been fixed.
