Subsampling an alignment file results in "user-provided comparison function does not correctly implement a total order" error

[tinyheero]

When trying to run:

export RUST_BACKTRACE=full
rasusa aln --coverage 30 HG002.bam

I get the following error:

I am using version rasusa-aln 2.1.0

Any idea what might be causing this error?

Can you provide a minimal file that produces this error?
