It might be best if you were to run an older version of GHC on such old systems, or to not use the threaded runtime. Downgrading from "highest" as the abovementioned workarounds are quite effective and newer, sensibly configured systems are not affected. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7926#comment:9> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
