I am consistently getting segfaults when I call any() on a particular array of 42364 elements. I will try to attach the array as a text file. There doesn't appear to be anything interesting about the array except that it does not have any zeros and appears to have a lot of smallish, duplicate values. I got the same segfault in 1.3.0, 1.4.1, and r8464 from svn:
