* Fix GC scanning of registers on x86_64 architectures.Reimer Behrends2015-05-071-0/+9
| | | | | | | It is possible for jmp_buf to not be word-aligned or addresses in the register dump to not be word-aligned. This can result in either addresses in registers being missed or even addresses on the stack past the register area not being scanned properly.
