[Octave-bug-tracker] [bug #65470] (instrument-control) ASAN crash during "test readline"

[Dmitri A. Sergatskov]

Follow-up Comment #1, bug #65470 (group octave):

Similarly, "test writeread" crashes:

octave:8> test writeread verbose

 a = udp ();
 a.remoteport = a.localport;
 a.remotehost = '127.0.0.1';
 a.timeout = 1;

 data = writeread(a, "hello");
 assert(data, "hello");
 clear a
