From bf24401a1f9cc8f4122405c7de1051d7823b6f0c Mon Sep 17 00:00:00 2001 From: Andrew MacIntyre Date: Wed, 1 Oct 2008 03:25:25 +0000 Subject: fix for issue 3862: test_array fails FreeBSD 7 amd64 FreeBSD 7's underlying malloc() is behaves differently to earlier versions and seriously overcommits available memory on amd64. This may affect other 64bit platforms in some circumstances, so the scale of the problematic test is wound back.
