commit deb274226783ab886bdb44876944e156757efe2b
Author: Daniel Beitler <dan@dablabs.com>
Date: Sun May 18 13:27:42 2014 -0400
msi: Prevent call to memset with a null pointer
in get_tablecolumns function.
Fix miscompilation with gcc >= 4.9
See https://bugs.winehq.org/show_bug.cgi?id=36139 for the upstream
bug report. There won't be a Wine 1.6.3 so we need to address this
anyway.
