running Arch Linux and I I've been using erlang 18.3 from a custom build
instead of the Arch package. As of about a month ago, everything was
fine including dialyzer and xref. I didn't do any work with erlang for about a
month and went back to it this week and found that I could no longer get
dialyzer or xref to work. I get complaints about missing debug_info

version of 18.2.1, but dialyzer thinks the files are invalid and if I
