Subject: [RFR] Store tearing

Hi,

memory-barriers.txt says:

  [on "store tearing"]

  "In fact, a recent bug (since fixed) caused GCC to incorrectly use
   this optimization in a volatile store.".

I was wondering if you could help me retrieve some reference/discussions
about this?

Thanks,
  Andrea
