From 1894e741f5a0cbc0818b0acbe0f7e45a22ab9107 Mon Sep 17 00:00:00 2001 From: Ramiro Polla Date: Mon, 13 Apr 2009 22:54:21 +0000 Subject: [PATCH] win32, dos: Work around a bug in the GNU toolchain. The bug[1] is exposed when gcc decides to put some data in a common section (i.e. data that will be used by more than one object). It will suggest the data to be aligned, but binutils >= 2.19 will fail to properly align it. Thus if the data requires any alignment greater than 4, the application will crash. The workaround prevents gcc from putting data in a common section, instead putting it in a properly aligned section.
