[erlang-questions] lager_trunc_io

[Andrew Thompson]

Ok, I think what you're seeing is the bug around improper list printing.
It is fixed in master, but not in 1.2.1.

I'm guessing either the 'last message' or the state contains something
like this: [[$a | {self(), left}]], which is causing the crash.

Anyway, I've backported the fix (and one other tiny fix) from master to
a new 1.2 branch (based off of the 1.2.1 tag) and tagged 1.2.2.

Thanks for the report.
