Could you try trunk or Ruby 2.4.1 and provide how to reproduce the issue?
I have armv7l-linux-eabihf environment and I'll try it.

Can confirm this occurs with 2.4.1, just install bootsnap and try and launch a rails application.

Tested on a H3 (armv7l)

Issue #13670 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Open to Feedback

`RubyVM::InstructionSequence#to_binary` and `RubyVM::InstructionSequence.load_from_binary` had bugs around word alignments.
I think the trunk has been fixed, couldn't you try it?
