```
pragma(msg, func!(int).mangleof);
extern(C++, `bar`)
{
void func(T)();
}
```
SEGV with DMD64 D Compiler v2.084.0-170-g16cf015ec
Moving `pragma` after the declaration, or using the non-string syntax does not.

@Geod24 created dlang/dmd pull request #10729 "Fix issue 19542: Forward reference segfault with string namespace C++ syntax" fixing this issue:
- Fix issue 19542: Forward reference segfault with string namespace C++ syntax
This segfaulted for some constructs, such as `pragma(msg)` and `enum`,
but not others, such as `static assert`, hence why the value isn't checked.
