<pre>Reduced test case:
Testcase:
#include <ostream>
struct Stream : public std::ostream {
Stream() : std::ostream() {}
};
int main() {
Stream crash;
return 0;
}
The code was compiled with clang 3.2 on Macos Snow Leopard. The libc++ used was
svn version r175274.
Valgrind stack trace (although from a little more involved case as valgrind
crashes on the above case).
