I've seen the same thing, and I had a suspicion that they mostly (only?) happen during parallel testing, e.g. "make -j5 check". That suspicion was reinforced when I was able to reproduce the error more relably via a few moreutils parallel runs like this: $ parallel -j 3 ./check-guile \ -- 00-repl-server.test 00-repl-server.test \ I found that the failure is due to a throw from write request and wrapping it like this: ;; Simulate an HTTP inter-protocol attack. (catch 'system-error (lambda () (write-request (build-request (string->uri "http://localhost")) socket)) (lambda what (format (current-error-port) "write-request exception ~s\n" what) (throw 'unresolved what))) does suppress the failure, while writing the same exception list seen in the original failures to stderr. I haven't actually looked closely at the test to see what the failure might mean.
