| 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] |
