reduced testcase
This is actually a bug that may have kept the SystemZ build bots red for some
time now, but due to vacations this has not been reported yet. So this is quite
urgent.
I have done a git bisect, and found that it seems that commit 463fa38
(trunk@311401) is the cause for this.
The attached reduced test case fails with that commit, but compiles if it's
reverted.
