I think we should apply the patch below to maint, as this is something
that can come up due to permissions problems. But I fear it won't
actually fix the test failure you are seeing; you will just see it die()
instead of segfaulting. However, the value of errno should give us a
clue about what is happening, so please try running the test again with
this patch.
Thanks, and I agree with the whole of the above paragraph, not just the
first sentence.
