This is a bug in perl. It's taking the (size_t) length of the string (1) times the (long long) repeat count (2**32-1), adding 1, and casting it to a size_t, resulting in 0, thus bypassing realloc'ing the string buffer for the result of the x. Then it gleefully tromps all over other things in memory. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
