> #define MALLINFO_FIELD_TYPE size_t

> The mallinfo struct has all its variable as size_t type

I am confused by this statement:

While malloc_stats() is certainly bugged by integer overflow (and that is in
particular despite `man 3 mallinfo` recommending it as non-overflowing
alternative), there doesn't seem to be a `MALLINFO_FIELD_TYPE` in glibc's
source code or git history, and the mallinfo struct has `int` inside.
