Bug#270823: atan2 never terminate for certains values of x,y on amd64

[Stéphane Magnenat <stephane.magnenat@epfl.ch>]

Package: libc6
Version: 2.3.2.ds1-16

atan2 never terminates for certains values of x,y on amd64.
This is a known bug, see:
http://sources.redhat.com/ml/libc-alpha/2003-11/msg00187.html

It is reproducable with;
#include <math.h>
int main(int argc, char *argv[])
{
        atan2(-.00756827042671106339, -.01792735857538728036);
        return 0;
}

This program runs forever with a debian sid amd64.

Here is my source.list:
deb http://bach.hpc2n.umu.se/pure64 sid main
deb-src http://bach.hpc2n.umu.se/pure64 sid main

deb http://debian-amd64.alioth.debian.org/pure64 sid main
deb-src http://debian-amd64.alioth.debian.org/pure64 sid main

This is very annoying, rendering our amd64 debian cluster totally unusable.

Thanks,

Steph
