Yeah, in general I agree with the article, the 'malloc all your memory' part is something I disagree with heavily. Outside of the fact that many malloc and calloc implementations don't particularly deal well with integer overflow[0], it introduces non-determinism into your code. MISRA C even forbids the use of dynamic memory allocation.

In fact, the environments where C shines oftentimes won't even have a dynamic allocator...

[0] Try allocating ((size_t)-1) bytes. Quite a few implementations will give you a pointer back! They'll add some space for a header, or round up the size to the nearest n-byte boundary. This problem's compounded by the fact people assume passing unsanitized input to malloc effectively sanitizes it.
