+Subject: [PATCH] exp_main_sub.c: Use PATH_MAX for path
+
+If expect was built from a long path whose length > 200, then it couldn't run:
+$ expect -c 'puts yes'
+*** buffer overflow detected ***: expect terminated
+Aborted (core dumped)
+
+Use PATH_MAX to fix the problem.
+
+Upstream-Status: Pending [Upstream seems dead]
