> Please unblock package bind9
> 
> This version fixes RC bug #778720 where bind9 randomly crashes on MIPS.
> The MIPS atomics implementation was buggy (register constraints were
> wrong and there were no memory barriers) and to fix it I just replaced
> it with C11 atomics. Only the MIPS part was replaced - this update
> should have no effect on other architectures.
> 
> I've tested the new version under heavy load for an hour or so on the 3
> MIPS architectures and it seems to be OK. Previously it would crash
> within 5 mins.
> 
> I've attached the debdiff. Since that isn't the easiest to read, I also
> attach the diff of lib/isc/mips/include/isc/atomic.h (the only file
> changed) between the version in testing and unstable.
> 
> There is another RC bug affecting bind9 (#860225), but that bug is not a
> regression from stretch.
