This isn't surprising. Read the documentation on the compiler flag you're using:

     *Warning:* if you use the `-malign-double' switch, structures
     containing the above types will be aligned differently than the
     published application binary interface specifications for the 386.

So, it's expected that -malign-double can lead to incorrect behavior.
