Hello c++ gurus,

I have two notes, about the behavior not specifed in the Jan 96 WP.

1) While stack unwinding the destructor (or function indirectly called from
the destructor) may try to do throw.

As seems to me WP says nothing about this case. Is it allowed ?
Is the behavior specified for this case ?

Example:

struct A {
	~A () { throw 1; }
};

void f ()
{
	A a;

	throw 2;
}

main ()
{
	f();
}

While stack unwinding control may come into the try-block.
Is it allowed ?
Shall this try-block hanlers be ignored ?

2) While stack unwinding the destructor may attempt to create
new objects, or arrays of class objects with non-trivial destructors
via operator new. Shall this outside exception affect creation of
new objects ? (Inner exception will cause destructor calls for all
already created base classes sub-objects and completely created array
elements.

Thank you in advance,
