This used to fail, but appears to have been fixed in the meantime.
A possible candidate for variant z2.f90 seems the fix for pr103413.
While looking at valgrind output with current trunk, I see a memleak
for the BOZ case that is obviously plugged by:
diff --git a/gcc/fortran/expr.cc b/gcc/fortran/expr.cc
index 4662328bf31..7fb33f81788 100644
--- a/gcc/fortran/expr.cc
+++ b/gcc/fortran/expr.cc
@@ -466,6 +466,10 @@ free_expr0 (gfc_expr *e)
mpc_clear (e->value.complex);
break;
+ case BT_BOZ:
+ free (e->boz.str);
+ break;
+
default:
break;
}
This might have been overseen during the BOZ rework.
Regtesting ...

Yep. It was missed by the guy that did the BOZ rework. ;-)
If it passed regtesting, it's ok to commit.

I think the BOZ rework was a greater step for mankind than the missing fix ...

It did. Will commit.

The BOZ memleak should be fixed with r13-6857-g833233a4aefc99.
There is another FE memleak which is the same for z1.f90 and z2.f90:
