It really is a bad idea to use malloc/calloc/alloc/free in C++
programs.  For one thing, this bypasses any constructors someone
may have written for the object you are making - and for another,
there is danger that you may allocate the space using 'malloc'
and someone else may not realise that an attempt to de-allocate
it with 'delete' (or allocated with 'new' and later 'free'd).

This can result in seriously error-prone code.

If you are writing in C++ you should really try to stick with
new/delete for *all* memory allocations.

Yeah - it's pretty standard these days.  The only system I've
seen recently that didn't support it was a rather ancient SGI
IRIX-based machine.
