pw-jack plugdata crashes when playing back large wav file

plugdata v0.9.2

plugdata is being run on the command line with 'pw-jack plugdata'

The attached patch reads in a small (~ 4MB) and a large (~60MB) sample into their respective arrays using [soundfiler]. It works fine when using 'Device Type ALSA' in the Device Configuration window. If set 'Device Type' is set to JACK, reading the small .wav works, but plugdata crashes if I try to read the large .wav.

The patch works fine with jack and vanilla pd (version 0.56.1, started with 'pw-jack pd').

Couldn't upload the longer sample here.

Issue can be recreated with this simpler patch (no wav files required, just a large array object).
