I found the issue! It was actually in my code - although it wasn't obvious from the error message. I was using c2i_ASN1-INTEGER for receipt validation. The reason why I didn't find it was that I included the underscore in my search string, whereas the method is c2i_ASN1-INTEGER in my code. Anyway, I substituted it with the d2i_ASN1-INTEGER and that fixed the problem.
