Trapping SIGWINCH with a proc works.

$ irb -f

irb(main):001:0> Signal.trap('SIGWINCH', proc { puts 'hola! from proc' })
=> nil
irb(main):002:0> hola! from proc # changing size of terminal window via GUI
irb(main):002:0> hola! from proc
irb(main):002:0> hola! from proc
irb(main):002:0> hola! from proc
puts

=> nil
irb(main):003:0>

But trapping SIGWINCH with a string (method name) causes error.

$ irb -f

irb(main):001:0> def hola; puts 'hola! from named method'; end
=> nil
irb(main):002:0> Signal.trap('SIGWINCH', 'hola')
=> nil
irb(main):003:0> hola! from named method # changing size of terminal window via GUI
irb(main):003:0> hola! from named method
irb(main):003:0> hola! from named method
irb(main):003:0> hola! from named method
puts
