Bug#452664: Can't upgrade libc6 in cowbuilder

[Bas Zoetekouw <bas@debian.org>]

Package: libc6
Version: 2.6.1-6
Severity: important

When I tried to upgrade my cowbuilder environment (i386 env on amd64),
I got this error:

Preparing to replace libc6 2.6.1-5 (using .../libc6_2.6.1-6_i386.deb) ...
Unpacking replacement libc6 ...
Setting up libc6 (2.6.1-6) ...
cowdancer: unexpected WIFEXITED status in waitpid
/var/lib/dpkg/info/libc6.postinst: line 142: /etc/ld.so.conf: Cannot allocate memory
dpkg: error processing libc6 (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 libc6


Note that I have plenty of memory free (about 1.5GB), so I guess
something weird must be going on:

[bas@cordelia]~> free -m
             total       used       free     shared    buffers     cached
