Hi!
|
|
<BR>
|
|
<P>What about just checking the backend name against "dll" while reading
|
|
<BR>
|
|
the dll.conf? This avoids that dll segfaults if dll is listed in the
|
|
<BR>
|
|
dll.conf.
|
|
<BR>
|
|
<P> If someone modifies the Makefile to preload dll or renames the library,
|
|
<BR>
|
|
he can't be helped, but this patch avoids that someone adds dll to
|
|
<BR>
|
|
dll.conf by accident.
|
|
<BR>
