521. Requirements for exceptions thrown by allocation functions

[Voted into WP at the October, 2006 meeting.]

According to 6.7.5.5.2 [basic.stc.dynamic.allocation] paragraph 3,

Any other allocation function that fails to allocate storage shall only indicate failure by throwing an exception of class std::bad_alloc (17.6.4.1 [bad.alloc]) or a class derived from std::bad_alloc.

Shouldn't this statement have the usual requirements for an unambiguous and accessible base class?

Proposed resolution (April, 2006):

Change the last sentence of 6.7.5.5.2 [basic.stc.dynamic.allocation] paragraph 3 as indicated:

Any other allocation function that fails to allocate storage shall only indicate failure only by throwing an exception of class std::bad_alloc (17.6.4.1 [bad.alloc]) or a class derived from std::bad_alloc a type that would match a handler (14.4 [except.handle]) of type std::bad_alloc (17.6.4.1 [bad.alloc]).
