+Subject: [PATCH] Don't segfault given string repeat count larger than 2^31
+
+E.g., this overflows INT_MAX and overruns heap memory:
+
+    $ perl -le 'print "v"x(2**31+1)'
+    [Exit 139 (SEGV)]
+
+(Perl_repeatcpy): Use the same type for "count" as our sole
+callers in pp.c: IV (long), not I32 (int).  Otherwise, passing
+the wider value to a narrower "I32 count"
