- 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]
- Signed-off-by: Robert Yang <liezhi.yang@windriver.com>
