>Description:
If "set [proc]title ..." command used inside "default" section of
configuration file then destroy argv[1] item - it has been set to NULL.
Later in processing, it (destroyed) argument is used as section name. It
caused SYGSEGV abend at line 311/systems.c (function ReadSystem).
Independent problem - the SetProcTitle function in command.c
- should be or shouldn't be rewritten using ``setproctitle(3)'' function ... ?
>How-To-Repeat:
Put "set title <any text>" command into section default of ppp.conf.
Run ppp with no "option" arguments but one or more "section name"
arguments.
