So if we have this

class A
  define_method :a do
    a
  end
end

and call A.new.a we got SystemStackError
but with alias

class A
  define_method :a do
    a
  end
end

when calling

x=A.new
x.a

in irb or

x=A.new
x.a; x.a

in pry gives

segmentation fault (core dumped)

But ruby -e 'class A; define_method :a do; a; end; end; A.new.a;'
gives segfault randomly

Initial issue is wrong a little.
So if we have this

class A
  define_method :a do
    a
  end
end

when calling in irb

x=A.new
x.a

or in pry

x=A.new
x.a; x.a

gives

segmentation fault (core dumped)

But
ruby -e 'class A; define_method :a do; a; end; end; A.new.a;'
gives segfault randomly

Could you try newer versions?

[liligga (Igor Grebennikov)]

Okay, ruby 2.1.2 gives everytime
abort (core dumped)

for
A.new.a
in pry, irb and ruby -e 'class A; define_method :a do; a; end; end; A.new.a'

2.1.2p207 seems working.
