Thanks for reporting this + the repro.vcf file. It seems like the hom-ref blocks in the file are causing this (although I don't fully understand how yet). Preprocessing with bcftools view -c 1 should fix the issue. Homref calls in the query VCF are not used by hap.py, so removing them should not affect the result.
Preprocess will be replaced with more up-to-date code in one of the next releases.
from hap.py.

Hello,
Any updates on this issue?
I am experiencing what is likely the same issue as well. I did not track down the source as thoroughly as OP but error appears to be the same (see below). I am trying to compare a sample VCF that has been imputed with the latest 1KG release (~61M SNPs) the the corresponding sample in the 1KG panel (how good is the library prep?) I get the same segmentation fault error in the preprocessing step which goes away if I prefilter the VCF for MAF (thus reducing the total number of SNPs to 3-6 M). I am running 31 samples in my batch and they all produce a segmentation fault and so this appears to be deterministic rather than random. Is there perhaps a theoretical maximum number of SNPs that hap.py can handle?
I am running hap.py with the provided Docker container, pulling each time, and have tested on a variety of EC2 instances, up to 128 GB of RAM.
I also instituted the suggested preprocessing step bcftools view -c 1 and that has resolved the issues. Is this still the best way to fix the issue?
Cheers,
Brian

30/12/2022 Update:
I preprocess the vcf with following script again:
bcftools annotate --rename-chrs chrRename.txt "$1" |
bcftools norm -m -any |
bcftools norm -f /mnt/d/epi25/hg38.fa.gz |
bcftools norm -a |
bcftools +fill-tags -- -t VAF |
bcftools view -T mytarget.bed -c 1 -i '(FILTER="PASS" | FILTER=".") & FORMAT/DP>10 & VAF>0.1' -Oz -o "$2"
And run the hap.py with following command:
docker run -v "/mnt/d/epi25/:/ref" -v "$PWD:/myfiles" -e "HGREF=/ref/hg38.fa.gz" -it hap.py /opt/hap.py/bin/hap.py /myfiles/$v /myfiles/$test -o /myfiles/$OUTDIR/$name -f /ref/hg38.fa.gz
I got a different error

I will be at this issue: #154
29/12/2022 Update: same error happens wih container from pkrusche/hap.py
I also have segfaults in preprocess step.
I have cloned from repo and build the docker myself.
I preprocess the vcf with this:
bcftools annotate --rename-chrs chrRename.txt "$1" |
bcftools norm -m -any |
bcftools norm -f /mnt/d/epi25/hg38.fa.gz |
bcftools +fill-tags -- -t VAF |
bcftools view -c 1 -i '(FILTER="PASS" | FILTER=".") & FORMAT/DP>10 & VAF>0.1' -Oz -o "$2"
my command looks like this:
docker run -v "/mnt/d/epi25/:/ref" -v "$PWD:/myfiles" -e "HGREF=/ref/hg38.fa.gz" -it hap.py /opt/hap.py/bin/hap.py /myfiles/$v /myfiles/$test -o /myfiles/$OUTDIR/$name

I encounter the similar CallProcessError in the latest version 0.3.15 and this problem can still be solved by the forementioned bcftools view -c 1. But alter bcftools view -c 1 reduced the original vcf.gz from 1.2G to approximately 100+M. I dont know if that is normal, but the result seems decent.

@LogCrab bcftools view -c 1 filters the lines if they're variants 0/1, 1/1 etc. That's why the size drops.
