[Quickfix-developers] r1491: nasty bug in Exception class

[Caleb E. <cal...@gm...>]

The Exception class constructor has a nasty bug.  Can you spot it?

/// Base QuickFIX exception type.
struct Exception : public std::logic_error
{
  Exception( const std::string& t, const std::string& d )
  : std::logic_error( detail.size() ? t + ": " + d : t ),
    type( t ), detail( d )
  {}

  std::string type;
  std::string detail;
};















SPOILER:

The ternary operator is using the "detail" class member, but it hasn't
been constructed yet!  Boom!
