Feature #20390
closedIssue with StringIO and chilled strings
Description
StringIO doesn't appear to handle chilled strings in a backwards-compatible way after 12be40ae
require "stringio"
sio = StringIO.new("")
sio.write("hello")
When not specifying a value for frozen-string-literal
, the empty string is chilled so I would expect to get a warning but also expect the write to complete.
Instead, the write fails as if the string is frozen:

./issue-stringio-frozen.rb:8:in 'StringIO#write': not opened for writing (IOError)
from ./issue-stringio-frozen.rb:8:in '<main>'
