Generating byte code from interface files leads to "silly extra arguments" in CorePrep
When a compiler with assertions enabled I see a lot of warnings of the form:
WARNING:
CorePrep: silly extra arguments:
$dm**>
Call stack:
CallStack (from HasCallStack):
warnPprTrace, called at compiler/GHC/CoreToStg/Prep.hs:674:21 in ghc:GHC.CoreToStg.Prep
When generating byte code from the interface files.
How serious is this warning?
