Description:
------------
Hi,

In /main/main.c:


381                tmp_value = (ini_entry->orig_value ? ini_entry->orig_value->val : NULL );
382                tmp_value_length = (int)ini_entry->orig_value->len;

That check on L381, "ini_entry->orig_value ? ini_entry->orig_value->val : NULL", implys that it ms possible for ini_entry->orig_value to be NULL.
However, the next line, it is dereferenced anyways.

Either the test is unneeded, or a test is needed for L382.


Thanks,

Patches
