Subject: apps/s_server.c: Add check for OPENSSL_strdup
X-Git-Tag: openssl-3.2.0-alpha1~2502
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a6a2dd9f60b3f3e93de1337ee84f9e8f33bc86a8;p=thirdparty%2Fopenssl.git

apps/s_server.c: Add check for OPENSSL_strdup

As the potential failure of the OPENSSL_strdup(),
it should be better to check the return value and
return error if fails.
