```
I believe GCC, deliberately as an extension, treats NSDMIs as within the
"immediate context" of a defaulted default constructor synthesis. So if NSDMI
instantiation fails the defaulted constructor gets defined as deleted instead
of issuing a hard error. Strictly speaking the code is ill-formed though IIUC.
There's probably an existing PR about this.
