I'm able to reproduce with just the system ghc: {{{ ghc Main.hs test.c -threaded -O1 -fforce-recomp [1 of 1] Compiling Main ( Main.hs, Main.o ) Linking Main ... }}} For me the program fails within seconds: {{{ $ time ./Main value mismatch value mismatch value mismatch value mismatch zsh: segmentation fault (core dumped) ./Main ./Main 2.19s user 0.20s system 67% cpu 3.553 total }}} I'm also able to reproduce the issue in a fedora virtual machine on the same physical machine using ghc 8.2.1 binaries downloaded from haskell.org. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14346#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
