Remedy
This issue can be avoided by not setting any telnet options for the curl command line tool (using the -t / --telnet-option command line option) or the libcurl library (using the CURLOPT_TELNETOPTIONS option) when telnet protocol is not meant to be used. If telnet protocol needs to be used with curl / libcurl, along with the NEW_ENV telnet option, ensure that no environment variable set via the NEW_ENV option has the name or value longer than 127 bytes.
