Looks like changes in Erlang regular expressions library broke Elixir again. Elixir stores internal binary representation of regular expressions in its compilation phase, and it breaks when Erlang changes this representation (which happens now and then, since it isn't supposed to be stable). I've already added a virtual package which reflects the version of the PCRE library Erlang uses (to indicate that Elixir requires rebuilding), but clearly it's insufficient. I'll have to increment its version on changes in erl_bif_re.c as well. As a long term solution, I'd suggest the maintainer of Elixir to reach out downstream and suggest not to use unstable interfaces fro regular expressions (not precompile them in advance).
