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

$ ./configure --host=ppc-linux --target=ppc --build=i686-linux --with-cc=powerpc-linux-gcc --with-ld=powerpc-linux-ld --with-endianness=little --enable-mini-agent

CC=/opt/arm-cross/usr/bin/arm-linux-gcc ./configure --host=i386 --target=arm-linux --prefix=/usr/local/arm/2.95.3/arm-linux --enable-add-ons --with-endianness=little --enable-mini-agent

I've sucessed port kexec/lkcd from 2.6.10/2.6.9 to 2.6.12FC4

ln -s /usr/src/linux/include/asm asm-generic linux as libpcap +pf_ring

ingore any warnning message.

you'll get a raw file .
