Are you sure it should be && and not ||? The logic seems to need "if the type is not a STRING derivative, or default not provided, or (default is neither BIT STRING nor OCTET STRING), then break". Correct?

BIT STRING -> etype : ASN_BASIC_BIT_STRING , default_value_type : ATV_BITVECTOR
OCTET STRING -> etype : ASN_BASIC_OCTET_STRING, default_value_type : ATV_BITVECTOR
IA5String -> etype : ASN_STRING_IA5String, default_value_type : ATV_STRING
However, ASN_BASIC_BIT_STRING and ASN_BASIC_OCTET_STRING do not have bits set with ASN_STRING_KM_MASK.
I admit that this is a little obscure but I tried to be safe for possible combinations I could figure out.
To simplify it, perhaps we could just check default_value->type against ATV_STRING and ATV_BITVECTOR.

I see. Would you say that ATV_STRING and ATV_BITSTRING cover all the possibilities we want to include here?
1. Modify asn1p_y.c and asn1p_y.y to fix an error that function _convert_bitstring2binary() always return NULL. 2. Add handling for default value with type ATV_BITVECTOR in function try_inline_default().
