Test gem against MRI 2.4.x

[PikachuEXE]

No description provided.

[PikachuEXE]

Got Segmentation fault ❌
I guess I will resubmit when 2.4.1 is out

[PikachuEXE]

Still got Segment fault
But I dunno what's the cause: the gem's C extension or Ruby

[PikachuEXE]

Running locally, got error as well, but not sure if it's the same error on Travis build:

ruby /users/pikachuexe/.rvm/gems/ruby-2.4.1/bin/rspec spec/seven_zip_ruby_spec.rb(14054,0x7000005c0000) malloc: *** error for object 0x7fa2f63b3400: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
[1]    14054 abort      bundle exec rspec spec/seven_zip_ruby_spec.rb

Thank you very much for your contribution.
I'll also investigate this issue further.

I tried running with MRI 2.5.0.rc1 and the test passed!
Maybe it's MRI related issue?
