In my hands, the readGenBank function in the genbankr package works very well with smaller GenBank files (<500 KB), but gives me a C stack usage error with any larger files.

In the example below chrI is 442Kb and chrIII is 638Kb. Am I doing something wrong and/or do the larger files need some pre-treatment?

I've tried other files as well - larger files always throw this error. Small files work just fine. I am currently running genbankr version 1.20.0 on R version 4.1.2.

Thanks!

    Translation product seems to be missing for 1 of 101 CDS annotations. Setting to ''
    No exons read from genbank file. Assuming sections of CDS are full exons
    No transcript features (mRNA) found, using spans of CDSs
