From 65fe4ef6f5674b0b52e797924990b090dbbd52af Mon Sep 17 00:00:00 2001 From: Alan Coopersmith Date: Mon, 1 Oct 2018 20:48:21 -0700 Subject: Remove last use of strcat If getcwd returned a string that exactly filled the prefix buffer, it could write the null terminator byte out of bounds. Instead, since the prefix is copied to a newly allocated string and never used again, just let the dsprintf() call take care of it.
