Solaris 8 x86
>Description:
If you compile static code, any code, with gcc on Solaris 8
on x86 architecture, the resulting binary will segfault
before reaching user code. 
To be more precise in _init ()
>How-To-Repeat:
# cat hello.c
#include <stdio.h>

int main(void)
{
        printf("Hello World!\n");
};
# gcc -static -g -o hello hello.c
# ./hello 
zsh: segmentation fault (core dumped)  ./hello

# gdb ./hello core
