-// This is a workaround for a bug in the Dinkumware

-// Calling basic_ios::init() multiple times for the
-// same basic_ios instance results in a memory leak
-// caused by the ios' locale being allocated more than
-// once, each time overwriting the old pointer.
-// This usually occurs in the following scenario:
-//
-// class MyStreamBuf: public std::streambuf
-// {
-// ...
-// };
-//
-// class MyIOS: public virtual std::ios
-// {
-// public:
-// MyIOS()
-// {
-// init(&_buf);
-// }
-// protected:
-// MyStreamBuf _buf;
-// };
-//
-// class MyIStream: public MyIOS, public std::istream
-// {
-// ...
-// };
-//
-// In this scenario, std::ios::init() is called twice
-// (the first time by the MyIOS constructor, the second
-// time by the std::istream constructor), resulting in
-// two locale objects being allocated, the pointer second
-// one overwriting the pointer to the first one and thus
-// causing a memory leak.
//
-// The workaround is to call init() only once for each
-// stream object - by the istream, ostream or iostream
-// constructor, and not calling init() in ios-derived
-// base classes.
-//
-// Some stream implementations, however, require that
-// init() is called in the MyIOS constructor.
-// Therefore we replace each call to init() with
-// the poco_ios_init macro defined below.
