I am trying to run prokaryotic annotation pipeline with a 5.2MB fasta file that contains a single sequence. But I am getting segmentation fault at start_site_curation step. When I trimmed the same fasta file into smaller sizes (1MB, 2MB) then run the pipeline respectively, they both passed. I ran start_site_curation.pl in debug mode; It seems successfully parsing input BSML file in subroutine parse_input_bsml. But segfault appears while exiting subroutine parse_input_bsml.
