I've met the following error::
Can't use an undefined value as a subroutine reference at /home/basiliscos/perl5/perlbrew/perls/perl-5.26.0/lib/site_perl/5.26.0/x86_64-linux/AnyEvent/Loop.pm line 248
when I run my program under perl 5.26.0, meanwhile under 5.20.3 it runs fine.
Any ideas where I should dig to?
Okay, the issue seems in the EV dependency; it should be optional, but installing it solves the problem. I hope it will be useful for somebody.
