 With "make target=x86", crash is built with -m32 to create a 32-bit x86 binary
 that runs on an x86_64 host, so kernel pointer sizes will always be the same
 as the crash binary. 
I was confused this.
I made the 2nd version of the patch and reflected your comments in it.
Could you review this?
Thanks.
