Subject: [PATCH] tctildr: fix segmentation fault if name_conf is too big
|
|
|
28cd4a |
|
|
|
28cd4a |
When strlen(name_conf) is too big and logging is set to at least DEBUG,
|
|
|
28cd4a |
tctildr_conf_parse will cause a segmentation fault. This happens when
|
|
|
28cd4a |
the unit tests are run with logging set to DEBUG. Hence, the logging
|
|
|
28cd4a |
call has to be done after the check for strlen(name_conf).
