Product: gcc
Version: 11.0

testcase
The following code seems to crash on gcc HEAD:
https://wandbox.org/permlink/O9ZzBf1aG9tTwTAl
It also doesn't compile with gcc 9.x or 10.x while clang 10 seems to have no
problems for reasons unknown to me.
Output:
```
during GIMPLE pass: *early_warn_uninitialized
prog.cc: In constructor 'BetterObject<CACHED>::BetterObject(const char*, int,
Handle&) [with bool CACHED = true]':
prog.cc:63:1: internal compiler error: Segmentation fault
