To reproduce the segmentation fault: {{{ $ cabal install vty-menu $ ghci -fno-ghci-sandbox ghci-coredumper.hs Prelude> die # Hold the Enter key for 10-30 seconds. }}} Replacing the second step by just `ghci ghci-coredumper.hs`, I sometimes get: {{{ *** Error in `/usr/local/haskell/ghc-7.8.3-x86_64/lib/ghc-7.8.3/bin/ghc': double free or corruption (fasttop): 0x00007f65b00118c0 *** Aborted (core dumped) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7789#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
