Issue #20595 has been updated by peterzhu2118 (Peter Zhu). The Ruby 3.3 backport PR is here: https://github.com/ruby/ruby/pull/11063 ---------------------------------------- Bug #20595: Corruption of encoding name string https://bugs.ruby-lang.org/issues/20595#change-108907 * Author: peterzhu2118 (Peter Zhu) * Status: Open * Backport: 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED ---------------------------------------- GitHub PR: https://github.com/ruby/ruby/pull/11062 enc_set_default_encoding will free the C string if the encoding is nil, but the C string can be used by the encoding name string. This will cause the encoding name string to be corrupted. Consider the following code: ```ruby Encoding.default_internal = Encoding::ASCII_8BIT names = Encoding.default_internal.names p names Encoding.default_internal = nil p names ``` It outputs: ``` ["ASCII-8BIT", "BINARY", "internal"] ["ASCII-8BIT", "BINARY", "\x00\x00\x00\x00\x00\x00\x00\x00"] ``` -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/lists/ruby-core.ml.ruby-lang.org/
