             Bug #: 14588
           Summary: Assertion failure with C++11 delegating constructor
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: akyrtzi at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

with this test case:
class Base
 virtual ~Base();

class Foo : public virtual Base
Foo(const void * inVoid);
virtual ~Foo();

Foo::Foo() : Foo(__null) {}// delegated constructor N1986
Foo::Foo(const void *inVoid) {}

$ clang -cc1 test.cpp -emit-llvm -o - -std=c++11
will hit an assertion:
Assertion failed: (!CodeGenVTables::needsVTTParameter(CGF.CurGD) && "doing
no-op VTT offset in base dtor/ctor?"), function GetVTTParameter, file
clang/lib/CodeGen/CGClass.cpp, line 302.
