From 1712e20a5ad7ead5981ce56b28121a9513b06dd2 Mon Sep 17 00:00:00 2001 From: Thierry Bastian Date: Tue, 19 Apr 2011 15:47:23 +0200 Subject: [PATCH] Fixed a crash on Windows XP with mingw in threaded-code The thread callback doesn't align the stack on 16-bytes on WinXP. That causes a crash when we call SSE code. So now we tell the compiler to force that alignment of the stack.
