Certainly.
For the code in comment 0, -fdump-tree-original shows:
l2 = (integer(kind=4)) s._len;
Apparently the _len component of the class container has kind=8.
The following patch manages to remove the conversion warning:

@@ -709,7 +709,7 @@ gfc_build_class_symbol (gfc_typespec *ts, symbol_attribute

- c->ts.kind = gfc_charlen_int_kind;
+ c->ts.kind = gfc_default_integer_kind;
c->attr.access = ACCESS_PRIVATE;
c->attr.artificial = 1;
}
However, instead of this, we should rather insert an explicit conversion to get
rid of the warning, I think.
