From f8ee67edb8e5fed34bf4d5208bce89ea8be1ac1e Mon Sep 17 00:00:00 2001 From: "marco.diiga" Date: Mon, 21 Mar 2016 06:04:43 -0700 Subject: Fix for unaligned automatic variable address in SSE routines. This used to work on linux but crashed on windows when rendering antialiased glyphs. I tracked the problem down to an alignment issue.
