I don't understand, sorry.
Were you able to repeat the user's error in your NFS tests?

I don't quite like the test case. It may have nothing to do with the
user's bug - we still don't know why it happens and we weren't able to
repeat it, as far as I understand.
If you just want to test that IO_CACHE doesn't read beyond end_of_file,
it's a good thing to test, I agree. But it should be a unit test.
So, please, remove this replication test and put a unit test for
end_of_file into unittest/sql/mf_iocache-t.cc
