As you say, it may be a timing-related bug. I tried running it on Fedora 37 x86-64 on a slow machine (AMD Phenom II X4 910e) and reproduced the timing bug. The output of 'make check' contained: GEN lisp/server-tests.log Running 7 tests (2023-02-23 09:45:51-0800, selector `(not (or (tag :expensive-test) (tag :unstable) (tag :nativecomp)))') make[3]: *** [Makefile:174: lisp/server-tests.log] Error 157 I guess "Error 157" means signal 29 (157 - 128), which is SIGIO on this platform. This was with Emacs master (commit 6411a9af03a4eb1a82db47a9642b11ba7edaaaf0).
