I had a look at the current trunk and the diffs leading up to it, and I can
confirm that the issue has not been fixed.
However, I don't have any specific test case.

Note also that for this kind of bug you can expect test cases to be
- very large and hard to understand
- appearing and disappearing in a pseudo-random manner as you make prima facie
  unrelated changes to other passes.
- For the trunk, or any branch with significant activity, it is likely that
  it takes longer to find a testcase than it takes that testcase to become
  obsolete because of some new check-in.
