However, it is not impossible. Several of my colleagues and I spent months trying to track down a bug where Python would occasionally crash with a segfault while iterating through large lists. Of course the problem only ever happened on customer sites, and not in our lab. I eventually tracked it down to a bug in glibc's realloc() implementation, where once in a blue moon it would fail to copy all the data into the newly-allocated buffer. It turned out to be a bug that had been found before, but had been closed as invalid a few months earlier: http://sources.redhat.com/bugzilla/show_bug.cgi?id=5743 The fix had then been applied about a week before I found it myself. I'm not sure that particular fix has found it into any of the major Linux distributions yet.
