alt Hacker NewsMy understanding of zero alloc is that there are no heap allocations i.e. use of a form of malloc. At least that has always been my experience, use of the stack is perfectly fine

But it puts sizeable arrays on the stack. That's not really better since instead of an out of memory exception it'll just corrupt the stack of on the majority of embedded implementations that don't have hardware stack protection in use or available.

Some stricter interpretations also require that maximum stack usage can be statically analyzed (ie. no recursion, no function pointers, no VLAs/alloca).
