Summary:                    [patch] 1.6.1.1: Memory handling error in main/pbx.c
(pbx_extension_helper)
Description: 
Due to Solaris x64 specifics, it won't accept NULLs as string. I think
Asterisk had similar problems before, and apparently it is still doing this
in some places. I found one of them today, since it was blocking asterisk
to start.

Basically, asterisk was segfaulting on every start, on the strlen()
routine.

Attached you can find gdb analysis on a core dumped and a patch that
solves this problem

    Solaris doesn't like NULL going to ast_log
    
    Solaris will crash if NULL is passed to ast_log. This simple patch
simply uses S_OR to
    get around this.
