The malloc attribute is used by compilers for optimizations purposes. It allows the compiler to decide that a pointer returned by such functions cannot alias anything.
The alloc_size attribute allows the compilers to emit warnings and/or add run-time instrumentation to catch buffer overflows. GCC can emit warnings based on this attribute, and clang has experimental support to instrument code to detect buffer overflows.
