Hello,
The fix for PR61831 committed recently [1] introduced/uncovered a NULLL
pointer dereference with iso_varying_string, because a generic symbol
(which
has a NULL result) is used as procedure symbol, instead of the
specific one.
Fixed by using esym if it's available.
Regression-tested on x86_64-linux. OK for trunk?

Hello,
I would like to backport the patch.
As the bug was discovered with the patch [1] above, the test
generic_30.f90 works on the branches, which don't have that patch.
Meanwhile, I have managed to find a test generic_31.f90 that exhibits a
wrong code already on the branch, which justifies the backport.
Regression tested on the 5 branch, OK for 5 and 4.9?
