I am receiving the same error in r151451, disappears in r151453 (20090905)
(trunk).
gcc 4.4 branch (r153538, 20091025) still has this problem, but needs adding of
-freorder-blocks-and-partition
This error appears only with testcase from #1, testcase #2 crashes only in 4.4
branch.
Testcase #4 crashes also only in 4.4 branch, but without
-freorder-blocks-and-partition
