No one knows. I suspect it ran out of memory since it appears that there was at least seven other GHC processes running concurrently on a machine with only 4 gigabytes of memory. However, seeing as there's no way to tell whether the OOM killer was invoked it's hard to know for certain. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14453 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
