So the table used in your test uses char(10000000), which is a
datatype that completes with spaces strings stored that have a length
shorter than the limit. So even if you store a string of n characters,
what will be stored are those n characters, followed by 10,000,000 - n
spaces.

And this test expects that result of column "name" does not contain
more 10k characters, so your data set is incompatible with your test,
explaining the crash you are seeing.
