I am receiving reports of nasty intermittent crashes when lispbuilder-sdl is run within a 32-bit Lisp (SBCL & CCL) on a 64-bit OS (Windows 7 and OSX). A 32- bit Lisp is used because the SDL library is 32-bit. No problems are reported using Lispworks/32-bit in Windows 7.

As for CCL, its 32-bit version might work badly on 64-bit version of Windows because CCL uses undocumented parts of NT API which behave differently in 64-bit version. E.g., they store pointer to TLS data in ES segment register but Wow64 subsystem does not preserve its value.

SBCL itself is unstable on Windows.
