The "open-output-pipe":"no duplicate" test has been hanging, on and off, and not completely reliably, for a few years. It's now doing so fairly reliably for me, and investigation shows that - the child shell process is in a tight loop (99% CPU) - the parent Guile process is stuck calling waitpid(). The problem is that the child hasn't got the SIGPIPE that the test intends, and so is continuing to echo "closed" forever; and Guile is waiting for it to terminate, forever. I haven't fully debugged the SIGPIPE problem, but it sounds very like what Chet Ramey describes here: http://old.nabble.com/Re%3A-SIGPIPE-not-properly-reset-with-%27trap---PIPE%27-p20985595.html. (And my version of bash is 3.2.39.) So, a fix should be to use something other than shell to implement the child; and it appears that this works. * check-guile.in (TEST_SUITE_DIR): Export. * test-suite/tests/popen-child.scm: New script file. * test-suite/tests/popen.test ("open-output-pipe", "no duplicate"): Use Guile for the child process, instead of shell.
