Subject: [musl] aio+fork bug test case
Date: Mon, 16 Nov 2020 00:04:32 -0500	[thread overview]
Message-ID: <20201116050432.GW534@brightrain.aerifal.cx> (raw)

[-- Attachment #1: Type: text/plain, Size: 315 bytes --]

I'm cleaning up my work spaces and found this draft test case for the
aio+fork bug fixed in 34904d830a9fd1f6fc47218f38c111698303d2fe. I'm
not sure how best to integrate it with libc-test, but posting it here
now so it's not lost. Probably should be edited to use pipe() rather
than relying on stdin blocking.

	aio_read(&cb);

	pid_t pid = fork();
	if (!pid) {
		close(fd);
		_exit(0);

	waitpid(pid, 0, 0);
}
