Orz solaris strlen core dump.

such code will drop a segment fault

#include <stdio.h> #include <string.h>

int main() { char *string = NULL;

printf("\nString length = %d", strlen(string)); return (0); }

to resolve this:

ugly and fast way is :

LD_PRELOAD_32="/usr/lib/0@0.so.1" export LD_PRELOAD_32
