High cpu load when usbtty device is unplugged without disconnecting before

[re-vax]

Hi!

I'm using this amazing tool CuteCom version 0.30.3-1+b2 on debian 11.6 / KDE-plasma

The problem appends when I'm connected to a device using a usb to serial adapter and when I unplug the dongle without clicking on the 'close' button. The result is a 100% CPU usage on the process.

with strace, CuteCom seems to loop on:

poll([{fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=15, events=POLLIN}], 3, 13515) = 1 ([{fd=15, revents=POLLIN|POLLERR|POLLHUP}])
read(15, "", 32768) = 0
poll([{fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=15, events=POLLIN}], 3, 13515) = 1 ([{fd=15, revents=POLLIN|POLLERR|POLLHUP}])
read(15, "", 32768) = 0
poll([{fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=15, events=POLLIN}], 3, 13515) = 1 ([{fd=15, revents=POLLIN|POLLERR|POLLHUP}])
read(15, "", 32768) = 0
poll([{fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=15, events=POLLIN}], 3, 13515) = 1 ([{fd=15, revents=POLLIN|POLLERR|POLLHUP}])
read(15, "", 32768) = 0

Any advice to go further in the debug process?

Do someone have the same issue (on same or other OS).

Thanks
