MSWin version doesn't matter; the OS design is fundamentally different
than unix, and clisp may need more customization. A stack overflow is
not uncommon, even on a system with plenty of free RAM; the OS
typically allocates a fixed stack size. Your bug report would
probably help the developers, but make sure you can reproduce it with
the latest version (2.48).
