test case:
# chroot /home/ia32
# cat bug.c
#include <stdio.h>

int main(void)
{
  FILE *foo = popen("ls","r");
  pclose(foo);
  return 0;
}
# gcc bug.c -o bug
# ./bug
# bin   bug    debootstrap  etc      lib    mnt  proc  sbin     srv test  usr
boot  bug.c  dev          home  media  opt  root  selinux  sys  tmp   var
# exit
# /home/ia32/bug
#

The same 32-bit binary work correctly outside the chroot (in the 
amd64-lenny system, with libc6-i386 installed).
