Yes, the problem still exists on 4.2 and mainline.  The patch is valid
in that it fixes a codegen deficiency, but it only works around this
bug.  The test case does not fail anymore, and getting another one to
fail may be tricky (it's a fairly rare bug, unfortunately).

A real fix is in the works, but it's not clear when it might be ready.
