The following works with libstdc++. Tested using current svn.

#include <sstream>
#include <cassert>

int main() {
  std::stringstream ss;
  long l;
  // This works
  ss.str("01777777777777777777777");
  ss >> std::oct >> l;
  assert(ss.fail());
  // This doesn't work
  ss.clear();
  ss.str("0000000000000000001777777777777777777777");
  ss >> std::oct >> l;
  assert(ss.fail());
}
