Bug#524064: Regression: compile failure on valid C++ code
Package: g++-4.3
Version: 4.3.3-7
Severity: normal
Compiling magics++, a new package for debian, I get:

make[4]: *** [EpsBufr.lo] Error 1
Relevant code:
196 ostringstream out;
197 tm convert = base_;
198 locale loc("");
199 out.imbue(loc);
200 const std::time_put<char>& tfac = use_facet<time_put<char> >(loc);
201 string format = "Forecast VT %A %e %B %Y %H UTC";
202 tfac.put(out, out, ' ', &convert, format.c_str(), format.c_str()+format.length());
This code compiles fine with g++-4.1.
