Scenario is the same as #5601: We're doing proxy authentication using basic auth, username "proxyuser" and an empty password. This works fine for us on 7.70.0, but breaks when upgrading to 7.71.0. Looking at the debug logs we see the following when responding to the proxy 407:
The base64 part decodes to
proxyuser:(nil), which doesn't look right.Looking at the code it's tempting to suspect that this
(nil)string originates from dprintf_formatf, possibly coming down from this printf?curl/libcurl version
7.71.0
