In EREs, left-brace is not to be interpreted as an ordinary character unless escaped. Using left-brace not as a part of a valid interval expression produces undefined results [1].

There is a patch-in-progress to fix our implementation to throw an error if left-brace is not used in a valid manner. This patch in particular should fix 20 elixir ports and unblock another 27 that were ignored as a result.
