Not sure what is the problem, perhaps someone who knows the code better can come
up with an explanation, but the following informally specified patch seems to fix
the issue for me (verified with 24 hald start-ups):
In hald-runner/runner.c, function run_request_run():
g_free (program_dir);
-if (r->input) {
+if (r->input && strlen(r->input) > 0) {
if (write(stdin_v, r->input, strlen(r->input)) != (ssize_t) strlen(r->input))
printf("Warning: Error while writing r->input (%s) to stdin_v.\n",
r->input);
close(stdin_v);
}
I hope that it's easy to apply this change by hand.
I will have a proper patch once I clean out all my debugging modifications from
the sources.
It looked like the issue was caused by the above write() call after a sufficiently
quick child process had already exited.
