>Description:
When tring to compile the given processed file, I get the following errors.

The most strange to me is that if I isolate the definition of QpException and the ostream&operator<<(ostream&o,const QpException &) in a single file, everything is fine. I guess there is a side effect but I couldn't find where does it comes from.

It works fine with g++ 2.95.3

 Hi,
 
 I'm the repoter of this (actualy not) bug.
 
 After trying all most stupid things possible, it appeared that a 
 #include <ostream>
 was missing (I couldn't imagine such a simple thing in a code from Pavel Krauz 
 but still).
 
 Sorry to have created this useless bug report.
 
 Cheers,
 
 Christophe de Vienne
