Here's a 10-line C++11 program, vastly simplified from a program I'm working on:
template <typename T> class Base { public:
template <typename S> Base(S x) {}
};
template <typename T> class Child : public Base<T> { public:
using Base<T>::Base;
};
template <> class Child<int> : public Base<int> { public:
using Base<int>::Base;
};
int main()
{
Child<int> child(8.0f);
}
MSVC 2015 outputs:
1>------ Build started: Project: MyProject, Configuration: Debug Win32 ------
1> filename.cpp
1>path\to\filename(10): fatal error C1001: An internal error has occurred in the compiler.
1> (compiler file 'msc1.cpp', line 1393)
1> To work around this problem, try simplifying or changing the program near the locations listed above.

N.B. MSVC 2015 support for inheriting constructors is new with that version.
I've already submitted a bug report on this, since at the very least the compiler should not crash. However, can I have confirmation that this is correct C++ usage/a workaround?
Bug report here
As mentioned in the comments, it seems to be a MSVC issue. Quickly compiled it with Clang and -std=c++11, no problems there.
