As others have noted, you are attempting to construct 2^32 words. Now
it's probable that you could run it on a computer with enough RAM to do
the job. (I work with ones that have 128 GiB.) But the indexes
involved are large enough that they are likely overflowing various
32-bit counters/pointers. So bash dies on an internal error in
malloc().
