Subject: [BUG] Directory glob picks up running or already-run scripts on OS X
Message-Id: <CEE58D57-A237-4451-8882-0AE0CE21DD58@gmail.com>

With zsh 5.2 or master running on OS X 10.11.5 or macOS 10.12 PB1, a =
glob for
directories could pick up scripts that are either running or have been
run. Note that this seems to only apply to scripts, not random =
executables
(e.g., an executable created by a C compiler). Here's a session that =
reproduces
the issue:

    $ cd $(mktemp -d)
    $ print '#!/usr/bin/env zsh' >script1
    $ print $'#!/usr/bin/env zsh\nprint -l */' >script2
    $ chmod +x script1 script2
    $ print -l */
    zsh: no matches found: */
    $ ./script1
    $ print -l */
    script1/
    $ ./script2
    script1/
    script2/
    $ print -l */
    script1/
    script2/
    $ print $'#include <stdio.h>\nint main() { printf("hello, world"); =
}' >hello.c
    $ cc -o hello hello.c
    $ ./hello
    hello, world%
    $ print -l */
    script1/
    script2/

I cannot reproduce this issue with zsh 5.0.8 on OS X, so something went =
wrong
in between. Unfortunately, due to some limitations I cannot test other =
versions
right now. I also cannot repoduce this issue on Linux with any zsh =
version
(including 5.2 or master), so this seems to be an OS X specific issue.=
