Subject: bug#30004: 27.0.50; call-interactively reads uninitialized memory
Date: Sat, 06 Jan 2018 12:31:51 +0100 [thread overview]
Message-ID: <m2a7xrte8o.fsf@gmail.com> (raw)
When passing a byte that would start a multibyte sequence,
`call-interactively` uses STRING_CHAR without checking whether the
entire multibyte sequence is actually part of the string. For example:
$ emacs -batch -nw -Q -eval '(call-interactively (lambda () (interactive "\xFF")))'
Invalid control letter ‘’ (#o775776, #x3fbfe) in interactive calling string
