Package: libc6-i386 Version: 2.24-11+deb9u1 Using gethostbyname in a fpc 2.4 application causes a crash with the following error:

This is the 32bit version of the library, meant for AMD64 systems. Homepage: http://www.gnu.org/software/libc/libc.html $ uname -a Linux stretch-vm 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux Removing the default ipv6 entires from the /etc/hosts file fixes the crash. echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6 has no effect. This seems to be a bug in libc6-i386? Older versions on Wheezy in a similar setup are running the same binary fine, even with the /etc/hosts entries present.
