In the thread on the tracecompass list, I also mentioned that the babeltrace utility itself ran out of memory when reading the file. That's actually my biggest worry. I got around the generator issue by flushing every 100K events.
I'll create a quick generator that shows the same issue and post it in a bit.

It should be easy to generate a random one with the class I mentioned below
and fill it with 16 million events.
Not if the problem is in the generator code ;).
BTW, two of the int fields are 5 and 10
bits respectively, but I'm not sure that matters (or at least it shouldn't).
Make sure to check the endian-ness of those fields.
What class? Not sure I see any reference to any.
Since you are generating CTF the error can be in the generator code. Please
provide either a trace reproducing the issue or a base reproducer. It will be
much easier overall than us trying to reproduce it blindly.
