I think, in fact, there's a good argument for ignoring the possibility of malloc (and calloc and realloc) failures for most PC code.  There is virtually no chance of failure in reality, and if you get one, there is almost never a sensible way to deal with it -

 I have had to deal and roll with malloc failures. It put the server in panic mode and it started killing connections that were already timed out, dumping some caches (freelists of regions, ect), ect... There is a way to recover.
 

There are applications where you can ignore malloc()-failures /
bad_alloc since they only allocate a small amount of memory or
a lot of small allocations which sum up to a small amount of
memory.
