emacs-27 'make check' fails on my Ubuntu 18.04.3 LTS x86-64 host. If in the test
directory I type 'M-x compile RET make lisp/comint-tests RET' I see the following:

make  lisp/comint-tests </dev/null
make[1]: Entering directory '/home/eggert/src/gnu/emacs/emacs-27-sc/test'
  ELC      lisp/comint-tests.elc
  GEN      lisp/comint-tests.log
Running 4 tests (2019-12-23 12:40:46-0800, selector `(not (tag :unstable))')
Buffer " *temp*-736584" has a running process; kill it? (yes or no)

and the test hangs indefinitely. The test should work even if standard input is
/dev/null.

There's a similar failure on Solaris 10 sparc. "make check" hangs here:

  ELC      ../../emacs-27.0.60/test/lisp/comint-tests.elc
  GEN      lisp/comint-tests.log

test/lisp/comint-tests.log says this, with no newline at the end of the file:

Running 4 tests (2019-12-23 17:39:32-0800, selector `(not (or (tag
:expensive-test) (tag :unstable)))')
   passed  1/4  comint-test-no-password-function (0.046805 sec)
Buffer " *temp*-851514" has a running process; kill it? (yes or no)

"truss" says that Emacs is hanging, reading from file descriptor 0.  So is
'cat'. Tests like this should not attempt to read from stdin, since the tests
need to run unattended.

Is this the same problem as bug#38813? A fix for that bug has been pushed.

Yes, Bug#38724 (not 38714) is fixed now for me. Thanks. Closing that bug.
