This was very likely due to a bug in the profile generation, where profile.threads[0].samples.length was incorrectly set to a value larger than profile.threads[0].samples.time.length.
So this issue may be invalid. Or we might want to turn it into something to make error handling slightly nicer in this case, if there's something easy to do.

The problem in this profile is that the Samples table is incorrect: samples.length is 1306 but each of its arrays has a length of 1050.
We could possibly do some sanity check at load time on the table lengths, which could at least give a better debugging experience.
