If I press C-\ (bound to term-send-raw) while some non-interactive
program is running in term-mode then the program crashes with nothing
suspicious in core dump. I've tried this in emacs 27.0.50 and emacs
26.1 started with -Q on Debian Linux.
So, to reproduce this, start term-mode with any shell, enter sleep 5 and
while the program is running press C-\. If I start program which expects
input from stdin (less, for example) then this bug doesn't appear.

I get this
$ sleep 5
^\Quit
$
But I get the same result in an rxvt terminal, so I don't think it's a
bug. https://en.wikipedia.org/wiki/Kill_(command)#Unix_and_Unix-like
says:
It is also common [...] for CTRL+\ (backslash) to be mapped to SIGQUIT,
which can force a program to do a core dump.

C-\ triggers SIGQUIT.
