[ensembl-dev] Question regarding plugin behavior under fork conditions in VEP

[Duarte Molha]

Dear Developers

I have created a simple plugin for VEP and adds to the annotation output
file a few fields from an input VCF (namely the score and the the genotype
fields for each processed individual.

It seems to work fine if I do not fork the process but using fork it dies
complaining about line
86.

If it isn't too much trouble could you take a look and give me some hints
why the $split_line[8] field might be undefined in the forked script? This
should always be there because it is the genotype field of a VCF file and
is included in all vcf lines.

Best regards

Duarte
