From a31426d3ea79f7b22d5000f2bfecb52f95246444 Mon Sep 17 00:00:00 2001 From: Allan McRae Date: Mon, 12 Jan 2015 12:47:38 +1000 Subject: makepkg: clear destination array in array_build If an already used array is passed array_build, some entries from the old array could be carried over if the old array was longer than the new one. Clear the destination array before adding elements to it to prevent this issue.
