Subject: bug#31274: 27.0.50; xdisp.c:7575: Emacs fatal error: assertion failed: IT_BYTEPOS (*it) == CHAR_TO_BYTE (IT_CHARPOS (*it))
Date: Thu, 26 Apr 2018 15:54:55 -0400 [thread overview]
Message-ID: <jwv8t99bv5c.fsf@iro.umontreal.ca> (raw)
Package: Emacs
Version: 27.0.50
I can reproduce the above assertion failure when I do the following:
% src/emacs -Q /usr/bin/perl -l .../elpa/packages/nhexl-mode/nhexl-mode.el -f nhexl-mode --eval '(setq word-wrap t)'
y
M->
The `y` is because nhexl-mode prompts the user to convert the buffer
to unibyte and is not directly relevant: you can use find-file-literally
instead and the result is the same. I used /usr/bin/perl in the above
example, but I could reproduce the same crash with "any" binary
executable such as /bin/gzip and src/emacs (tho with some it doesn't
crash immediately).
Obviously, word-wrap in a binary buffer is not very meaningful, but
that doesn't justify a discrepancy between charpos and bytepos.
Stefan
