The issue here is that `char *` is not allowed to alias
with `anyType *`.  With gcc-10 in Fedora this now started
to cause real problems and loading stats module segfaulted.

Actually I can't see in standard (C11 6.5 par.7) that using `void *`
is guaranteed to be correct, but at least it seems fine with gcc,
and e.g. some standard functions like posix_memalign() use it
in the same "dangerous" way.
