haskell - "cabal install happy"导致内存溢出。 (GHC 7.8.2)

Question

在过去的几天里，我一直在努力让正确安装感到高兴，虽然我发现获得 cabal install happy 很有挑战性。不仅仅是错误(通过安装 happy-1.19 和 apt-get 并将 /opt/happy/1.19.3/bin 添加到 PATH )，现在它通过源运行直到它到达 ProduceCode (15/18)，似乎进入了一个无限循环。它会累积内存，直到我点击 Ctrl+C或在整个系统无响应时关闭电源。

我想我记得这对 GHC-HEAD 根本不是问题，但我不想使用 head，因为它似乎每隔几天更新一次，需要我不断重建我的包，除非我有什么技巧'不知道从 head 迁移至head+1 .

“对我来说，它适用于 -O 或 -O2 -fno-spec-constr ，但是当我尝试使用 -O2 构建时，我在 ghc 达到 4gb RAM 后杀死了它”
