So, you create 128 bits (16 bytes) of data of UUID, but then you save into

Hello,
I don't believe such bug can exist and no one has noticed it yet :)
Anyway, thanks for your suggestion. I've checked it - works fine.
Actually, the code is this:

The table schema description said "TEXT", so one expects the UUID is in its
text for

1 in 16 of the generated UUID's could have this, which roughly matches
your 4% failures.
