This looks like a compiler bug. No matter what the C++ problem is, the 
compiler shouldn't assert or crash.

Did you try using a template/template partial specialization forward 
declaration:

#if defined(__SUNPRO_CC)
template<typename T>
class HashCountedSet;

template<>
class HashCountedSet<const char*>;
#endif

before the method declaration.
