I got a segfault with a recent version of gcc 4.2 on x86_64. It has gone away recently but after investigating when it was introduced and fixed I got the impression that this is a latent problem.
With the attached testcase, I can reproduce this segfault starting with r115200 until r115711. As far as I can tell, neither of those changes are related so I think the problem is latent.
