[Issue 15473] C++ mangling problem
https://issues.dlang.org/show_bug.cgi?id=15473 --- Comment #5 from Manu --- *sigh*, like everything, this only appears when the case becomes sufficient complex, and reduction takes ages. I was hoping you'd able to look at the difference in the mangled names, and infer what the problem is by the difference in attributes. Assuming you understand the mangled names, it should be pretty revealing. --

--- Comment #3 from Manu ---
Here's another case:
C++:
?CreateImplInternal@Component@ep@@IEAAPEAXU?$BaseString@D@2@U?$SharedMap@U?$AVLTree@UVariant@ep@@U12@U?$Compare@UVariant@ep@@@2@@ep@@@2@@Z
D:
?CreateImplInternal@Component@ep@@IEAAPEAXU?$BaseString@D@2@U?$SharedMap@U?$AVLTree@UVariant@ep@@0U?$Compare@UVariant@ep@@@2@@ep@@@2@@Z
The difference being that same little '0U' which is meant to be 'U12@U' again.
C++ declaration:
namespace ep {
class Component : public RefCounted, public IComponent
{
void* CreateImplInternal(String ComponentType, Variant::VarMap initParams);
};
}
D declaration:
extern (C++, ep) class Component : RefCounted, IComponent
{
void* CreateImplInternal(String componentType, Variant.VarMap initParams);
}
In both cases, the function involves, Variant::VarMap, which expands to:
C++: ep::SharedMap>>
D: SharedMap!(AVLTree!(Variant, Variant, Compare!Variant))
That's the same type as the return value in the first issue, with the same
problem in the symbol name.
This is a pretty long symbol name, but the missing 'U12@' seems deterministic.
