hum, I must be missing something.. but I dont see how you're
using this state except for smal window within:
if (auxtrace_snapshot_is_toggled()) {
-> auxtrace_snapshot_process();
if (!auxtrace_snapshot_is_error())
-> record__read_auxtrace_snapshot(rec);
but no other place queries or depends on this state
also the switch_output code does not seem to use this transition at all
thanks,
