Quite odd. I had a closer look at the locking functions, and I noticed that spin_*lock() functions do not have a "memory" clobber. In my understanding of gcc's behavior, that lets it move memory operations outside the critical section, even with the volatile qualifier (which just means that the assembly part shouldn't be optimized away). At least in all other spinlock implementations I know there is such clobber. That could very well explain the oddity above (as well as other random things happening from times to times). Samuel
