Description

A string with forced encoding used a buffer for reading from a File becomes frozen unexpectedly if #to_sym is called on it

file = File.open('some_file')
str = ""
str.force_encoding(Encoding::US_ASCII)
str.frozen? # => false
file.read(2,str)
str.frozen? # => false
str.to_sym
str.frozen? # => true

If the force_encoding is skipped str doesn't become frozen, same with reading from the file.
