invalid memory address or nil pointer dereference

[komalsrathi]

Hi,

Here are the details of the issue I am facing. I have attached drive links to the query and annotation vcf files (they are both very small).

conf:

[[annotation]]
file="gnomad.exomes.r2.0.1.sites.subset.no-VEP.nohist.tidy.vcf.gz"
fields = ["AF", "AF_AFR", "AF_AMR", "AF_ASJ", "AF_FIN", "AF_NFE", "AF_OTH", "AF_SAS"]
names = ["gnomad_AF", "gnomad_AF_AFR", "gnomad_AF_AMR", "gnomad_AF_ASJ", "gnomad_AF_FIN", "gnomad_AF_NFE", "gnomad_AF_OTH", "gnomad_AF_SAS"]
ops=["max", "max", "max", "max", "max", "max", "max", "max"] 

Gnomad annotation (minimal subset):
https://drive.google.com/open?id=1Adra0ddMWJEeGbEy9_CEWhYXDEsVkLt6

Minimal query file (vcf.gz):
https://drive.google.com/open?id=1i4ndYYhn81iSxg6aV7kXX8WFXX_kZd3Y

Command:

vcfanno -lua rare-disease.lua rare-disease.conf 27571P-gatk-haplotype-annotated.vcf.gz | gzip -c > 27571P-gatk-haplotype-gnomad-annotated.vcf.gz

Error:

hi, sorry for the delay and thanks for the full data to reproduce. I am looking into it.
You can get around this, it seems, by using -p 1 argument to vcfanno. I'll have a look at a real fix.

I pushed a fix for this, it will be out in next release. You can circumvent by either using a single thread, or by using a bgzipped query file (yours was just gzipped). Thanks again for reporting.
