Bug#173913: more details on this

Hello,

I have installed libc6_2.3.1-6 in 5 systems this morning with no problems.
But in another one, it happened the same as reported in this message:
function not implemented. All of them are i386 machines. I could not run
dpkg --configure, neither dpkg -i or apt-get, or ls. Stracing ls, it seemed
to die in a call to getdents64, but it looks like no *64 function is
working:

_exit(1)                                = ?


Downgrading manually to libc6_2.1.3-5 solved the problem, as reported too.
This system was updated just as the other ones that did work before: apt-get
dist-upgrade to today's sid in the mirror, so all other package versions are
exactly the same. The only difference I can find is that the system which
has the problem with newer libc6 is that the other systems are running
kernel 2.4.18 or 2.4.19 and this one runs 2.2.19.

I hope this helps.


Kind regards,
