regex, stringbuf and MSVC++ 6

What follow is the descriptions of a possible bug.

Unfortunately I'm using MSVC++ and ran into some unexpected behavior
using boost::regex_format and a stringbuf. I compiled 1.27.0 without
the /Oa flag as suggested in the installation notes.

In summary, this works:
   stringbuf line;
   ...
   string tmp = line.str();
   if (regex_match(tmp, matchInfo, linerx)) {
      string name = regex_format(matchInfo, "$1");
   }
but this doesn't:
   stringbuf line;
   ...
   if (regex_match(line.str(), matchInfo, linerx)) {
      string name = regex_format(matchInfo, "$1");
   }
By "doesn't work" I mean that 'name' has spurious characteres.

If this might be a bug, let me know and I'll track it down to a small,
compilable example.
