Hi,

It seems to work, thanks!

I've verified on debian sparc64 that make and make check succeed when I checkout b28464a, while make check fails with bus error when I checkout 87a656a.

I've also verified that the debian src package version 1.6.0-1 builds successfully on sparc64 with patch b28464a applied locally, and that the same package with the same patch applied still builds successfully on amd64. Those are the only archs I have access to.

I have limited experience with C development, and zero experience with alignment issues, DTC or its test suite, so I can't be of much help here...

Best regards,
Tom
