That won't work. Some allocated strings will come from other libraries
and must be freed with the standard free(), and possibly vice versa (you
need to give a pointer freeable with standard free() to something). So
it's generally not possible to switch the whole program to use an
incompatible allocator like that.

If the system lacks any way to allocate aligned memory freeable with
standard free() then there is no clean solution.
