I'm not sure what do you mean by "a Store", minimal repro goes like this:
https://godbolt.org/z/8z1vqf6Wv.
We get the crush as soon as try to get default binding of a copied struct.
The fix may be a little "light-minded", I'll try to investigate more on the
issue with other NonLocs that could get beside ConcreteInt.
