+Subject: [PATCH] Fix initialization in test/iodelay.cpp
+
+jack_latency_range_t is
+
+struct _jack_latency_range {
+    jack_nframes_t min;
+    jack_nframes_t max;
+};
+
+and jack_nframes_t is
+
+typedef uint32_t        jack_nframes_t;
+
+so it's unsigned. Initialising it with -1 is invalid (at least in C++14). We cannot use {0, 0}, because latency_cb has
+
+   jack_latency_range_t range;
+   range.min = range.max = 0;
+   if ((range.min != capture_latency.min) || (range.max !=
+       capture_latency.max)) {
+       capture_latency = range;
+   }
+
+so we must not have {0, 0}, otherwise the condition would never be true.
+
+Using UINT32_MAX should be equivalent to the previous -1.
