Paul,

Can you share more info on the problem on x86_64?  What kind of failure you see?  What is OS and HW?  Can you share a reproducer?

The code you are talking about is quite ancient. I doubt anybody can guarantee the code correctness, but we don't see any problems in many years of testing. I cannot tell anything on AArch64, but if we could reproduce the problem on x86_64, we'd be happy to investigate it.

Thanks,
Andrey
