Hi Hector,

I don't think this is due to packed structures, because
-mno-unaligned-access tells the compiler that unaligned fields in
packed structures should be accesses by breaking the unaligned access
into smaller aligned ones, so this would not cause an alignment abort.

What can cause an alignment abort despite -mno-unaligned-access is
dereferencing a badly aligned pointer, and this is probably what
happens here.

Amicalement,
