Sorry, being more explicit about the above line, which I realized later
is rather vague:

  --  Pulseaudio config file was the standard one for system daemon mode
      ("system.pa") except I removed the "module-detect", and replaced
      it with:

	load-module module-alsa-source device=hw:0 tsched=0
	load-module module-alsa-sink device=hw:0 tsched=0

      ...and added the following rtp receiver line at the end
      for my test case which demonstrates the crash at the first
      resampler update:

	load-module module-rtp-recv sap_address= sink=alsa_output.hw_0


In a different test, I tried a few other receiver sinks ("module-combine"
and "module-null-sink") and the problem occurs there as well.
