That depends ... If you can override the abort() function with an
error handler, then I'd say it is OK.

Remember that only about 1 in 10 memory allocations in a program use
malloc.  The other 9 use the stack, and effectively call 'abort()' if
they fail with no opportunity to override.

(For me, of course, all this just points to the desperate need to use
proper programming languages for writing critical software ..  In 2008
we shouldn't even be having a discussion about memory management, in
the same way we don't discuss laying out the blocks on the hard disk
any more)
