Subject: Check conversion return in ASN1_INTEGER_print_bio.
X-Git-Tag: OpenSSL_1_1_1-pre9~71
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=35c9408108f3608eb572acd7f64a93cf4f43f4f6;p=oweals%2Fopenssl.git

Check conversion return in ASN1_INTEGER_print_bio.

Also streamline the code by relying on ASN1_INTEGER_to_BN to allocate the
BN instead of doing it separately.
