I think he's saying that the command doesn't appear to complete. i.e. the session just sits there working and "never" finishes. The question is whether, if given long enough, it will complete.
I can confirm that it works for me on Windows7 with t of length 1000, 10000, and 100000. Length 100000 takes ~75 seconds. For t=: 1e6 you may just have to wait a long time!! Note I haven't installed the zlib binary, so this is just using the J code versions. (Running on Linux with the libz.so present, takes about a second.)
