openssl/libressl ocsp error in 6.1 stable

[Renaud Allard]

Hello,

I noticed in my logs things like this.
May  1 03:00:02 isildur openssl: vfprintf %s NULL in "%s %2d 
%02d:%02d:%02d%.*s %d%s"

It comes down to this command to fetch ocsp response:
openssl ocsp -respout ocsp.der -no_nonce -issuer chain.pem -cert 
cert.pem -url http://ocsp.int-x3.letsencrypt.org -header "HOST" 
"ocsp.int-x3.letsencrypt.org" -verify_other chain.pem -rother chain.pem

Best Regards
