Package: libmsgsl-dev Version: 4.0.0-2.1 Severity: important Forwarded: https://github.com/microsoft/GSL/issues/1134
gsl::not_null and std::variant from GNU's libstdc++ are not interoperable. The std::variant::emplace function of a template containing gsl::not_null of any type crashes due to infinite recursion. Check the following code. int i = 0; std::variant< std::monostate, gsl::not_null<int*> > v; v.emplace< gsl::not_null<int*> >(&i); See full example here -> https://godbolt.org/z/KTP9EdMzf It will be neat to workaround the failure in the libmsgsl-dev package. At least, a fix of this error is required to solve Bug#1050903.
