http://d.puremagic.com/issues/show_bug.cgi?id=7375 --- Comment #3 from Walter Bright bugzi...@digitalmars.com 2012-01-30 01:20:02 PST --- The failure definitely happened between 2.056 and 2.057. Anyone care to run the git binary diff thing? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

In druntime/src/rt/cast_.d, the addition of a name compare saying the classes are the same in _d_isbaseof and _d_isbaseof2. Not sure what the right fix is. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

(I remember seeing it when it was committed) Sorry I didn't get around to looking into it earlier. I think the solution is to do a compare on the full mangled name of the class, but I can't see anywhere it's exposed in the classinfo so it would need to be added. This should probably be delayed until after the release and the commit reverted. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

A one file version:
---
class A {}
class B(int i) : A {}
class C(int i) : B!i {}
template DerivedAlias(int i)
{
alias B!i DerivedAlias;
}
alias DerivedAlias!22 X;
void main(string[] args)
{
A foo = new C!11();
//auto dummy = cast(B!11)foo;
assert(cast(B!22)foo is null);
}

Sorry, I forgot to finish minimizing b.d. The properly minimized b.d is:
module b;
Base getEleven()
{
Base foo = new MoreDerived!11();
return foo;
}
class Base {}
class Derived(int i) : Base {}
class MoreDerived(int i) : Derived!i {}
template DerivedAlias(int i)
{
alias Derived!i DerivedAlias;
}
