As a suggestion: On ia64 the context is 128-bit aligned due to having FP registers. I would suggest to order the structs so that both the context and sigset_t are 16-byte aligned on 64-bit platforms. Alignment of sigset_t to 16 bytes allows machines that have 16-byte atomic operations to read/write the sigset_t atomically. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
