[I sent this message a week ago but did not get a response.]
It's possible that this is something that fundamentally cannot be
fixed, but maybe not. Would someone please take a look, DTRT, and
then ack?

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the address@hidden mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
* emacs -Q
* M-x shell RET
(assuming sh-type command interpreter)
* in *shell* buffer:
$ PS1='x -y $ '
x -y $ ls -l >/dev/null
x -y $
Once the ls command is entered on the second line, the -y in the
prompt gets highlighted the same way that the -l in the ls command
gets highlighted.
doing `C-u C-x =' on the `y' in the prompt on the last line gives:
character: y (121, #o171, #x79, U+0079)
charset: ascii (ASCII (ISO646 IRV))
code point: #x79
syntax: w which means: word
category: a:ASCII l:Latin
buffer code: #x79
file code: #x79 (encoded by coding system iso-latin-1-unix)
display: by this font (glyph code)
-outline-Bitstream Vera Sans Mono-normal-i-normal-normal-11-82-96-96-c-*-
iso8859-1 (#x79)
There is an overlay here:
From 240 to 247
font-lock-face comint-highlight-prompt
There are text properties here:
face font-lock-comment-face
field output
fontified t
inhibit-line-move-field-capture t
rear-nonsticky t
Doing the same on the second, now fontified, prompt gives:
character: y (121, #o171, #x79, U+0079)
charset: ascii (ASCII (ISO646 IRV))
code point: #x79
syntax: w which means: word
category: a:ASCII l:Latin
buffer code: #x79
file code: #x79 (encoded by coding system iso-latin-1-unix)
display: by this font (glyph code)
-outline-Bitstream Vera Sans Mono-normal-r-normal-normal-11-82-96-96-c-*-
iso8859-1 (#x79)
There are text properties here:
face font-lock-comment-face
field output
font-lock-face comint-highlight-prompt
fontified t
inhibit-line-move-field-capture t
rear-nonsticky t
I've seen this in other comint-like buffers as well (*sql*). Is there
a way to protect/prevent the prompt string from being font-lock'd?
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/emacs/etc/DEBUG for instructions.
