This patch replaces Balloc() by eBalloc() which calls __assert_func() on
failure which in turn calls exit() and/or abort()

Is this really a sane thing to do? After all, assertions should be used to
detect logically impossible situations but not as a general replacement for
error handling.

Shouldn't those library functions simply report the error by returning NULL to
the caller and let the application handle the situation?
