From 2f91880f3afb3cc521111dfcc99b214c77aa97a1 Mon Sep 17 00:00:00 2001 From: Sergio Durigan Junior Date: Thu, 8 Jun 2017 16:58:25 -0400 Subject: Fix possible bug when no args have been provided to the executable Hi, This bug is related to: On stringify_argv, we have to check if args[0] is not NULL before stringifying anything, otherwise we might do the wrong thing when trimming the "ret" string in the end. args[0] will be NULL when no arguments are passed to the inferior that will be started.
