Loading this file causes Julia to segfault on master branch.

Reducing the array being loaded by one row avoids the segfault.
Appears to be a memory corruption?

Likely dup of #20103

I think this one involves a long concrete tuple type that we can easily add a fast path for. #20103 I think is trickier.
