That's not the only problem. There is also a bug in FreeBSD: although
_SC_GETPW_R_SIZE_MAX is defined, actual sysconf variable is not
implemented, sysconf(_SC_GETPW_R_SIZE_MAX) returns -1, this value is
later passed to alloca(), and the result is passed to getpwuid_r, which
causes it to fail in a strange way, marked above with "Yopt!".

This bug is only arises on FreeBSD/amd64, somehow it is passed through
on 32bit arch.
