For a non-static local variable with __attribute__ ((aligned (0x40))) gcc 4.3.3
makes no attempt in the generated code to align the variable and emitts no
warning about that. Same if the type has the attribute specified instead of
the variable (the types I tried were an array of 6 uint64_t's or a struct
containing the array as a member).

Can you try if it works with gcc 4.4.0?

Yes! I haven't executed it but correct assembly seems to be emitted for x86.
Marking INVALID.

Reopen it since it only works for x86 in gcc 4.4.
