The main issue of 'type-less' standard C allocations is that there is no check on allocated type possible. This is a serious source of annoyance (and crashes) when making some low-level structs non-trivial, as tracking down all usages of these structs in higher-level other structs and their allocation is... really painful. MEM_[cm]allocN<T> templates on the other hand do check that the given type is trivial, at build time (static assert), which makes such issue... trivial to catch. NOTE: New code should strive to use MEM_new (i.e. allocation and construction) as much as possible, even for trivial PoD types. Pull Request: https://projects.blender.org/blender/blender/pulls/135747
