Attached is a more minimal example which crashes. With debugging on the original problem gave me these problems (on different runs): Most frequently just Segmentation fault (with no stack trace) Occasionally this: {{{ bench: internal error: ASSERTION FAILED: file rts/sm/GCAux.c, line 44 (GHC version 7.10.2 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Aborted (core dumped) }}} and more rarely this: {{{ bench: internal error: WEAK object entered! (GHC version 7.10.2 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Aborted (core dumped) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11108 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
