FTR: I tried to reproduce the crash, but couldn't get far enough:
running "M-x telega" requires some server, which I don't have, and
won't install. So someone who has that installed will need to debug
this and tell me how come this code crashes.
The abort is in this code in bidi.c:
/* Don't move at end of buffer/string. */
else if (bidi_it->charpos < (string_p ? bidi_it->string.schars : ZV))
{
/* Advance to the next character, skipping characters covered by
display strings (nchars > 1). */
if (bidi_it->nchars <= 0)
emacs_abort ();
bidi_it->charpos += bidi_it->nchars;
if (bidi_it->ch_len == 0)
emacs_abort ();
bidi_it->bytepos += bidi_it->ch_len;
prev_type = bidi_it->orig_type;
}
The backtrace points to the first call to emacs_abort, but since this
is an optimized build, it could be the second one as well. These
situations "should not happen", ever. So I must understand what kind
of buffer or string text we bumped into that caused this, it should be
something highly unusual.
