The fix for aligned_alloc is likely to land along with support for FreeBSD. I
will close this item then. If you feel that there is a strong need for
reallocarray please open a new item and I'll take a look.

Currently, in practice I don't see much benefit in adding reallocarray.
The glibc implementation just uses realloc:

So does the FreeBSD

Finally, I did start writing some regression tests, for instance
// example from here https://en.cppreference.com/w/c/memory/aligned_alloc
#include
#include
int main(void)
{
int *p1 = malloc(10*sizeof *p1);

I'll look at reallocarray another day on FreeBSD (not a high priority for me).
For aligned_alloc, I don't think that this will work well. The problem is that
aligned_alloc and and memalign alias the same function on
