[Message part 1 (text/plain, inline)]

This is Emacs master commit 65090ec691d9bd82a9ba3bd25756227e0d43bd80 
dated today, running on Fedora 42 x86-64 on an old, slow CPU (an AMD 
Phenom II X4 910e). The failure symptom with "make -j5 check" is in 
test/lisp/textmodes/ispell-tests/ispell-tests.log, a copy of which I am 
attaching.

Please show the output of "ispell -vv" on that platform.

Since you say the test fails with -j5, does it mean it succeed when
you don't use a parallel Make run?

AFAICT, the test in question does this:

  (defun ispell-tests--some-valid-dictionary (backend)
    "Return some dictionary name working for BACKEND."
    (cond ((string-equal backend "ispell")
	   (with-temp-buffer
	     (call-process backend nil t nil "-vv")
	     (let* ((s "LIBDIR = ")
		    (slen (length s))
		    (_ (search-backward s))

so parallel execution should not affect it, since call-process waits
for the process to exit.

It outputs the following line:

@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.8.1)

No, it fails the same without -j5.

So it's actually Aspell, in which case the failure is inevitable.  But
I wonder why this test is being run with Aspell at all, since the code
is not supposed to do that:

  (defun ispell-tests--some-valid-dictionary (backend)
    "Return some dictionary name working for BACKEND."
    (cond ((string-equal backend "ispell")
	   (with-temp-buffer
	     (call-process backend nil t nil "-vv")
	     (let* ((s "LIBDIR = ")
		    (slen (length s))
		    (_ (search-backward s))

and

      (with-temp-buffer
	(ispell-tests--letopt
	    ((ispell-program-name (ispell-tests--some-backend)))

	  (let ((test-dictname (ispell-tests--some-valid-dictionary ispell-program-name))

So if this passes the tests and conditions when the speller is Aspell,
we should amend the conditions.  What does ispell-tests--some-backend
return in your case?

It returns "ispell" as noted below.

$ src/emacs -batch -Q -eval '(progn (load "'$PWD'/test/lisp/textmodes
/ispell-tests/ispell-tests-common.elc") (message "%S" 
(ispell-tests--some-backend)))' 

Loading 
/home/eggert/src/gnu/emacs/static-checking/test/lisp/textmodes/ispell-tests/ispell-tests-common.elc... 

available backend is:ispell 

"ispell"
