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

Yes yrashk your right.
Solaris / OpenSolaris does not support NULL to printf.
I did a very small example program and found that strlen does not cause
issue.
See below:

#include <stdio.h>
#include <stdlib.h>

int main (int argc, char **argv)
{
   char *a = "stuff";
   char *b = "";
   char *c = NULL;

   if (argc == 2)
      printf("a:%s,b:%s,c:%s",a,b,c);
   else
      strlen(c);

   return 0;
}
