There are none for this particular problem. I've done a lot of sparc  
fixes after 2.1.4 was released and this problem is now rarer, but  
still occurs every now and then. It's caused by indeterminism in the  
register allocator. See

I haven't seen it happen at all lately in 2.3.1, but I have no idea  
why that is (and whether this is pure coincidence, whether the bug is  
still there but somehow hidden by other code, or whether it is  
actually fixed there.
