It's actually not libacl, but libc.  The 2.3.5 changed something
related to having an executable stack (I don't quite know the details,
but searching Debian lists for recent posts on "executable stack"
should turn up many references).  However, the problem is only
triggered on older 2.4 Linux kernels (I believe 2.4.27 is not
affected, but 2.4.18 is) or if the kernel has the pax patch included.
