one more idea - the address looks as a wrap over kernel memory pages
when there is no page allocated for 4A7A2ED000, but a page is there for
4A7A2EC000, where the target is being copied, it can be an
"over-optimized" version of memcpy() or something like that
I already debugged this kind of crash with older glibc in RHEL.
