#7567: invalidateModSummaryCache throws exception if ms_hs_date is 0 -----------------------------+---------------------------------------------- Reporter: edsko | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.6.1 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- Comment(by edsko): Incidentally, the exception is an error, so it is only thrown when ms_hs_date is forced (ModSummary does not use strict fields). -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7567#comment:2> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
