c++: ICE with defaulted comparison operator [PR94478]
Here we ICE because early_check_defaulted_comparison passed a null
ctx to same_type_p. The attached test is ill-formed according to
[class.compare.default]/1, so fixed by detecting this case early.
PR c++/94478 - ICE with defaulted comparison operator
* method.c (early_check_defaulted_comparison): Give an error when
the
context is null.
* g++.dg/cpp2a/spaceship-err4.C: New test.
