The deadliest file in Emacs history |

Gentleman, I reveal to you the deadliest file in the history
of Emacs.
It is so deadly that it must be QP encoded, else, well,
Fatal error 11: Segmentation fault
Backtrace:
emacs[0x50a5fe]...
/lib/x86_64-linux-gnu/libpthread.so.0(+0x11fb0)[0x7fc827b75fb0]
/usr/lib/x86_64-linux-gnu/libotf.so.0(OTF_drive_gpos_with_log+0x2a)[0x7fc828527a2a]
/usr/lib/x86_64-linux-gnu/libm17n-flt.so.0(+0x24f2)[0x7fc8280e04f2]...
It is so deadly that once restored from QP, only emacs -nw can safely open it.
If you use X-windows, even doing "! cat"
(! runs the command dired-do-shell-command)
or just plain
$ emacs DEATH
will crash your emacs.
No matter if you do
# su - nobody
or even LC_ALL=C emacs ...
for the cleanest environment.
Oh yeah, here it is.
$ cat DEATH.qp
=E0=B2=B9=E0=B3=86=E0=B2=9A=E0=B3=8D=E0=B2=9A=E0=B3=81
It is so deadly that even in M-x shell,
just doing
$ qprint -d DEATH.qp
will fry your emacs.
emacs-version "25.2.2"
Debian emacs25 25.2+1-6

To summarize:
This is an issue in the libotf library that Emacs uses.
It will be fixed in a future libotf release.
In the meantime, it can be worked around in Emacs by adding
"Noto Serif Kannada" to face-ignored-fonts.
