digitalmars.D.bugs - [Issue 19260] New: extern(C++) `T* const` mangling


          Issue ID: 19260
           Summary: extern(C++) `T* const` mangling
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1

This function:
  void deallocate(T* const ptr, size_t count);

Is critical for linking STL, but I can't mangle the function.

D should obviously declare the function as:
  void deallocate(T* ptr, size_t count);

Which is semantically identical in terms of usage, but the mangling of the
const pointer is different and therefore can't link.

What can we do?
I can't use pragma(mangle), because `T` is a template arg, and could be

This has stopped me in my tracks :/
