[Bug middle-end/15654] New: ICE with -O2 -fno-tree-dominator-opts

[green at redhat dot com]

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.

$ gcj --encoding=UTF-8 -fassume-compiled
