optparse duplication

[kddnewton]

require "optparse"

opt = OptionParser.new
opt.def_option(/^[^-]/) {}

begin
  opt.parse(["-t"])
rescue OptionParser::InvalidOption
  p $!.args
end

I'm not sure what the issue here is. Both Ruby and prism outputs ["-t"] for me.

@peterzhu2118 really? Ruby outputs ["-t"] for me and prism outputs ["-t", "-t"]

This works for me on ruby/ruby@731367d0ab.

I found a minimum repro:

calls = []
begin
  begin
  rescue RuntimeError
    calls << 1
  else
    calls << 2
    raise RuntimeError
  end
rescue RuntimeError
end

calls

It should output [2] but outputs [2, 1].
