From fb30cabe61862f640f0e99f214dc2777a8ec1b35 Mon Sep 17 00:00:00 2001

Subject: common: Properly forward arguments from die to error

Also allow this function to be called without arguments, in which case,
don't call error at all. Some uses of this function wrongly assumed
that this was already allowed.
