Hi all,

I think I have found the cause of the problem.

Commit b46b8f19c9cd435ecac4d9d12b39d78c137ecd66 partially fixed alignment=
=20
issues but does not ensure that all 64bit alignment requirements of=20
sparc32 are met. Tests have shown that the redzone2 word can become=20
misallignd.

I am currently working on a posible fix.

Regards
 =09Mark Fortescue.
