I am compiling a large amount of java code with -fno-tree-dominator-opts in
order to work around a bug, when I cam across this problem. No small test case
yet, but I'll update the offending source file right away.

This is caused in loop header copy pass.
Zendek, can you look into this?
I do not have a small testcase yet either.

The problem actually is in tailcall optimization, where we remove the call
that defines iCodeTop_8, but not the assigment iCodeTop_9 = iCodeTop_8
that follows it. I am testing the patch for the problem.

the machine I tested it on crashed, so I am rerunning the tests. Here
is the patch, if someone wants to try it.

Thanks Zdenek. This patch appears to get me past the problem!
(now I have a new problem, and will file a new case)

Zdenek did you retest the patch? If so can you submit it as I think you can reproduce the ICE when
bootstrapping with -O2 -fno-tree-dominator-opts.
