In gensample_to_vcf (vcfconvert.c), add the missing bcf_hdr_add_sample(header, NULL) finalization call after the sample addition loop, matching the pattern used in haplegendsample_to_vcf and other converters. In indel_ctx_type (vcfstats.c), check faidx_fetch_seq return for NULL before dereferencing. If the chromosome is absent from the reference, return the default indel length with nrep=0, nlen=0 instead of crashing with a NULL pointer dereference.
