hmm, while you discovered clearly a bug, your patch is buggy too.


quoting the pd documentation of [route]:
"Route checks the first element of a message against each of its
arguments, which may be numbers or symbols (but not a mixture of the two.)"

this means that both [route 5 bang] and [route bang 5] are illegal!

however, i believe that pd should complain about illegal creation
arguments for route and it must not swallow the bang in the [route 5
bang] example, but rather send it to the reject outlet.

i have attached a patch (against pd-0.38-4) that will give refuse to
create [route] with illegal arguments and that rejects "bang"
(zero-lengthed lists) when in float-mode.
