Description Eli Friedman 2009-07-30 19:09:16 PDT 
Testcase:
struct A { ~A(); };
template <class T> struct B {};
template <> struct B<int> : private A {};
B<int> foo;

Crashes with the following assertion:
clang-cc: /home/eli/llvm/tools/clang/lib/AST/DeclarationName.cpp:306: clang::DeclarationName clang::DeclarationNameTable::getCXXSpecialName(clang::DeclarationName::NameKind, clang::QualType): Assertion `Ty->isCanonical() && "Can only build C++ special names from canonical types"' failed.

I'm not able to reproduce this one with trunk. I get another assertion if I try to emit code, but it does not look related.
Comment 2 Douglas Gregor 2009-08-20 19:06:04 PDT 
I bet the bug was fixed when we introduced canonical type smart pointers; getCXXSpecialName is now (statically) guaranteed to get a canonical type. Closing!
