[Bug c/30622] New: char *p; p = "str"; puts "str" into rodata

["vda dot linux at googlemail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

char p;
int main() {
        p = "str";
        return 0;
}

If anyone will try to assign something to p[0] and if rodata is write
protected,
we'll segfault. Assembly:

        .file   "t.c"
        .section        .rodata.str1.1,"aMS",@progbits,1
.LC0:
        .string "str"
        .text
.globl main
        .type   main, @function
main:
        pushl   %ebp
        movl    %esp, %ebp
        movl    $.LC0, %eax
        movb    %al, p
        xorl    %eax, %eax
        leave
        ret
        .size   main, .-main
        .comm   p,1,1
        .ident  "GCC: (GNU) 4.1.1"
        .section        .note.GNU-stack,"",@progbits
