That's why I said "reasonably sized". If you malloc() inside a file
parser, malloc() based on unverified user input, or malloc() huge
buffers, adding a check is an absolute necessity.
These are cases with a clear action to take on error.
But adding a check to every random malloc(sizeof some_struct) is
counter-productive. If a small malloc() fails, chances are that your
error handler will fail, too.
Let the operating system take care of these cases.
