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]
