With the MSVC compiled curl and DEBUG_CONFIG I got this:
  GOT: --netrc-optional
  PARAM: ".6"
  ...\_curlrc:4: warning: '--netrc-optional' had unsupported trailing garbage

when _curlrc does *not* end in a newline. I can't see why, but this
code in parseconfig() (at line 2070):
      /* pass spaces and separator(s) */
      while(isspace((int)*line) || isseparator(*line))
        line++;

is reading past the 0-termination of 'aline'. Patch follows:
