Is core.atomic not saving and restoring a register it should?
Doesn't look like. I've reviewed this code to check for that. I
think it could be one of two things:
1. A DMD codegen bug that's not saving the registers properly.
2. An extremely subtle concurrency bug that's causing codepaths that
"can't happen" to be executed, meaning DMD doesn't save the registers
properly because the relevant codepaths "can't happen".
If it is the second case, then it might also exist as a problem in DMC
which suggests that it might be open to attack via the methods this guy
is developing/using:
