I share your concerns, but I'm also sympathetic to the changes that
the Taller Technologies team are trying to make, to allow libstdc++ to
be more useful in exception-free systems.
At the very least the patch to doc/xml/manual/configure.xml must
document that this option enables behaviour that violates the standard
and so produces a non-conforming implementation. It should probably
also explain how to use the resulting implementation, so that users on
embedded systems who might want to enable this know how to write a
suitable new-handler.
If there is a problem with programs too easily getting themselves
into an infinite loop because of improperly written new handlers
it might be worth proposing a change to C++ to make the minimum
number of iterations the loop must make before giving up
implementation-defined. That way this could be handled the same
way regardless of the environment.
