	Strange problem. My program works perfectly well when compiled
with no optimizations and crashes with `Page fault at...., error 0004'
when compiled with `-O1' or `-O2'. The function it stops at performs
rotation of points. It does use some inline assembly, but everything
is `volatile', so shouldn't be messed with by the compiler. Any ideas what
it's all about? It's not likely I've found a bug, is it?
