It's unlikely to be a compression issue. Is this the latest samtools
and htslib release?

I don't see how specifying a single region could ever give duplicated
positions (and some missing) in VCF though, hence this is likely a
bug!

It is worth testing bcftools mpileup, just to be sure it's not been
fixed.  The samtools mpileup -v code has migrated to bcftools now and
it's deprecated in samtools.  There are some minor command line
differences and maybe other tweaks, so it's worth checking it there.

If it still fails with the latest bcftools code then can you please
file a ticket on github?

Apologies for the problems.
