Guennadi, you are probably right. The reason is that the gcc is aligning embedded structures always to a word boundary on ARM. I didn't know about that and didn't care for while removing the packed attributes. Here is a webpage with some explanation about it: http://netwinder.osuosl.org/users/b/brianbr/public_html/alignment.html I will write a patch over the weekend, which should solve the issue.
