It seems the bug has reappeared in GCC 4.1.2.  Here is what I obtain:

        .file   "bug.c"
        .text
        .p2align 4,,15
.globl assign2
        .type   assign2, @function
assign2:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $20, %esp
        fldl    12(%ebp)
        fstps   -20(%ebp)
        movl    8(%ebp), %eax
        flds    -20(%ebp)
        fchs
        fstps   -4(%ebp)
        flds    -4(%ebp)
        fchs
        fstps   (%eax)
        leave
        ret
        .size   assign2, .-assign2
        .ident  "GCC: (GNU) 4.1.2 20070626 (Red Hat 4.1.2-13)"
        .section        .note.GNU-stack,"",@progbits
