GCC 10 says
t.C: In instantiation of 'BetterObject<CACHED>::BetterObject(const char*, int,
Handle&) [with bool CACHED = true]':
t.C:61:31: required from here
t.C:53:45: error: use of deleted function 'Handle::Handle(const Handle&)'
53 | , BetterObjectBase(lc_, ln_, env) {}
| ^
t.C:9:5: note: declared here
9 | Handle(const Handle &) = delete;
| ^~~~~~
and GCC 11 doesn't crash for me, but you didn't tell us the exact compile
options or the target you are using. So GCC 11 accepts the testcase for me.
