在过去的几天里，我一直在努力正确安装，虽然我发现让cabal install happy不仅仅出错（通过将happy-1.19与apt-get一起安装并将/opt/happy/1.19.3/bin添加到PATH）很有挑战性，但现在它会贯穿源代码，直到到达ProduceCode（15/18），似乎进入了一个无限循环。它会积累内存，直到我按下Ctrl+C，或者当整个系统变得没有响应时关闭电源。
我想我记得GHC-HEAD根本不是问题，但我不想使用它，因为它似乎每隔几天就会更新一次，需要我不断地重建我的包，除非有一个我不知道的从head迁移到head+1的技巧。

"对我来说，它适用于-O或-O2 -fno-spec-constr，但当我尝试用-O2构建时，我在ghc达到4gb RAM后杀死了它"
