4Subject: [PATCH] exp_main_sub.c: Use PATH_MAX for path
5
6If expect was built from a long path whose length > 200, then it couldn't run:
7$ expect -c 'puts yes'
8*** buffer overflow detected ***: expect terminated
9Aborted (core dumped)
10
11Use PATH_MAX to fix the problem.

13Upstream-Status: Pending [Upstream seems dead]
