Description Meta 2015-12-05 00:14:10 UTC 
The following program causes the compiler to segfault. It compiles successfully if `Test.Name.Space.test` is not accessed.

struct Test
{
	extern(C++, Name.Space)
	{
		enum test = 0;
	}
}

void main()
{
	assert(Test.Name.Space.test == 0);
}

I think it segfaults because there's no concept of standalone enum values in C++ and the compiler does not now what to do.

I would guess that you have hit some of the "Internal Compiler Error"s in https://github.com/D-Programming-Language/dmd/blob/master/src/cppmangle.d
