Allow destructors to throw when compiling in >= C++11 #767

Peter-Levine · 2017-02-08T00:01:55Z

In C++11 and later, destructors are marked noexcept(true) by default. All throws become calls to terminate(). To enable the original intent of the throw, such destructors (and if virtual, those of its parent classes) need to be explicitly marked noexcept(false) when compiled in a dialect >= C++11.

Explicitly mark destructors that throw as "noexcept(false)" when compiling in a post C++11 dialect.

Thanks! Interesting change in C++11. Is it possible to macro this in one place, for example:

In a header file:

#if __cplusplus >= 201103L
#define NO_EXCEPT_FALSE noexcept(false)
#else
#define NO_EXCEPT_FALSE
#endif

Everywhere else:

Bindable_t::~Bindable_t()
NO_EXCEPT_FALSE
  {
  	BindingBag.erase (Binding);
  }

…)" for destructors where needed

Yeah. Updated it. Putting it in ext/binder.h works fine on my end.
