Maybe I should remark, that on my system the assembler output looks I little
different than yours.
Good:
.L2:
pushl %edi
fildl (%esp)
addl $4, %esp
fstpl (%esp)
call Square
fstpl (%esi,%ebx,8)
addl $1, %ebx
cmpl $50000000, %ebx
jne .L2
Bad:
.L2:
movl $0, (%esp)
movl $1083129856, 4(%esp)
call Square
fstpl -8(%esi,%ebx,8)
addl $1, %ebx
cmpl $50000001, %ebx
jne .L2
