When I run this command in a Linux terminal (konsole) and change then the windows size nothing happens.I have a second Linux in a virtual machine. There it works as expected.trap -- 'echo changed size' SIGWINCHWhat could be the reason that SIGWINCH doesn't work any more?__Example: when I run this script on a normal Linux it outputs SIGWINCH! and dies as soon as the windows is resized. On the problem Linux resizing the windows has no effect - the script keeps running.#!/usr/bin/env perluse strict;use warnings;$SIG{WINCH} = sub { die 'SIGWINCH!!!' };my $sum;for my $i ( 1 .. 10_000_000 ) {    printf %0.3f\n,  $i / 31;}SIGWINCH is working again. I don't know why.
