When loading a VCF file, one of the records is ignored. The missing record has a 4094 byte record immediately prior to it and any change to the length of that record makes the loading succeed again. Changing the content of the prior record without changing the length also causes the record to fail to load.

 

Reproduction steps:

names(readVcf("repo.vcf"))

Expected output:

[1] "gridss9_272646b" "gridss9_31852o" 

Actual output:

[1] "gridss9_272646b"
