(I don't know about this one)

yes, that's a bug which surfaced in #301, thought it was gone in #302, and _should_ be gone in #303

I'd try putting "-e" before the "/bin/zsh", which moves it away from the bug noted.
(actually, the trailing "-l" doesn't look right either)

fwiw, when I compile #301, #302 and #303 for Cygwin, I don't see the bug.
However, I was able to analyze it on Linux with valgrind...
