New Revision: 228119
URL: http://svn.freebsd.org/changeset/base/228119
Log:
In build_volume(), check if arrays is allocated before traversing its
items. While parsing the arrays input, it's possible that we reach the
error path before initializing the 'arrays' pointer, which in turn leads
to a NULL deference.
