[cc65] Possible optimizer errors with -Oi

I have now two separate Lynx programmers that have some code that fails 
with the -Oi switch in 2.13.9 but work in 2.13.3. Without the -Oi switch 
it also works in 2.13.9.

Unfortunately the bug is not easy to isolate as it disappears when the 
code gets smaller.

The bug could best be described as video glitches. In one game the 
playing area jumps up by 8 pixels and the down again.

Any ideas of how to pinpoint this?

Or does someone else have problems with the latest code in the svn?
