Also affects self-compiled pd-0.47.0 from Miller's site so it isn't a Debian-specific issue.

$ pd -version
Pd-0.47.1 ("") compiled for Debian (0.47.1-3) on 2016/11/28 at 20:56:10 UTC

Steps to reproduce:

$ qjackctl
start jackd at 48000 sample rate, or modify the line below
$ pd -noprefs -jack -channels 2 -r 48000 -nogui -send "pd dsp 1"
error: JACKerror: SuspendRefNum error
error: JACKerror: JackClient::Execute error name = pure_data_0
error: JACK: server shut down
^CPd: signal 2

Pd starts up and connects to JACK successfully without -nogui, or without -send "pd dsp 1".

Problem also occurs with [loadbang]--[; pd dsp 1(, which was where I noticed it.

Workaround 1 (requires modifying patches): [loadbang]--[delay 1]--[; pd dsp 1(

Workaround 2 (requires modifying startup scripts): create a loader patch that opens the real patch after a [loadbang]--[delay 1], then the real patch's [loadbang]--[; pd dsp 1( is late enough not to break. And load the loader patch instead of the real patch from the command line.
