Description
GH-PR: https://github.com/ruby/strscan/pull/20
This is a strscan
issue.
I'm not sure the best way of how to handle bundled libraries tickets since they are Gemfied.
So I created this ticket just in case.
This code makes segmentation fault.
$ ruby -v

require 'strscan'
string = 'ruby'
scnanner = StringScanner.new(string)
pre = Module.new do
def byteslice(*args)
end
end
string.singleton_class.prepend(pre)
scnanner.charpos
