Did you intend for the \n in this assignment to be a literal newline?
Every shell with which I tested treats it instead as an escaped 'n'.

By the way, are the embedded newlines actually important to the test
itself, or are they just for human consumption if the test fails? I
ask because I was curious about how other tests create large files,
and found that a mechanism similar to your original (but without the
pitfalls) has been used. For instance, t1050-large.sh uses:
printf "%2000000s" X >large1 &&
which is plenty portable and (presumably) doesn't have such demanding
memory consumption.
