+Subject: [PATCH] [perl #113980] pp_syscall: "I32 retval" truncates the
+ returned value
+
+I noticed today that syscall(9, ...) (mmap) doesn't work for me.
+
+The problem is obvious, pp_syscall() uses I32 for retval and the
+"long" address doesn't fit into "int".
+
+The one-liner below should fix the problem.
