I think on some platforms they move over to the 32-bit setting in the thread struct before the address space is cleared out for exec. And if that is the case, I agree with Andi, that is the real bug that needs to be fixed. I recall that at one point Al Viro put some fix into binfmt_elf.c that caused the thread compat type to change too early like that and it made sparc64 explode so I knew to correct it immediately and this happened years ago. I just checked and ia64 sets thread.task_size in SET_PERSONALITY() which is just fine, similarly for ppc64. So I really wonder how this problem can arise.
