Don't bother, I raised the "bug report", but I also wrote in
http://gcc.gnu.org/ml/gcc-bugs/2001-12/msg00332.html
Using an explicit manipulator
i >> std::setbase(0) >> x;
or
i >> std::oct >> x;
causes the number to be read correctly. I suppose it's table 89 in
27.4.4.1 that determines that dec is the default? I didn't expect
that.
As I said, I wasn't expecting dec to be the default, but it looks like
it conforms to the standard.
