Nicolas Iooss 6707526f1f libsepol/cil: avoid freeing uninitialized values 
cil_resolve_ast() begins by checking whether one of its parameters is
NULL and "goto exit;" when it is the case. As extra_args has not been
initialized there, this leads to calling cil_destroy_tree_node_stack(),
__cil_ordered_lists_destroy()... on garbage values.

In practise this cannot happen because cil_resolve_ast() is only called
by cil_compile() after cil_build_ast() succeeded. As the if condition
exists nonetheless, fix the body of the if block in order to silence a
warning reported by clang Static Analyzer.

Build dependencies on Fedora:
yum install audit-libs-devel bison bzip2-devel dbus-devel dbus-glib-devel flex flex-devel flex-static glib2-devel libcap-devel libcap-ng-devel pam-devel pcre-devel python-devel setools-devel swig xmlto redhat-rpm-config

To build and install everything under a private directory, run:
make DESTDIR=~/obj install install-pywrap

To install as the default system libraries and binaries
(overwriting any previously installed ones - dangerous!),
on x86_64, run:
make LIBDIR=/usr/lib64 SHLIBDIR=/lib64 install install-pywrap relabel
or on x86 (32-bit), run:
make install install-pywrap relabel

This may render your system unusable if the upstream SELinux userspace
lacks library functions or other dependencies relied upon by your
distribution.  If it breaks, you get to keep both pieces.

To install libsepol on macOS (mainly for policy analysis):
cd libsepol; make DESTDIR=/usr/local PREFIX=/usr/local install

This requires GNU coreutils (brew install coreutils).
