Thanks for the pointer. Unfortunately I'm still unable to reproduce the bug. I went ahead and ran the script you pointed to which repeatedly creates and removes the second snapshot. At the same time I was performing i/o to the logical volume origin. I let these run for well over 30min. Every once and a while I'd see messages like:
device-mapper: Error reading/writing snapshot
device-mapper: snapshot is marked invalid
However, I never witnessed the bug reported here. How often do you see this? And are you able to readily reproduce it? Thanks.
