「堆棧構建」隨機失敗

Question

當我使用stack build構建一個包時，它在安裝依賴包期間隨機失敗。下面是一個例子錯誤消息：

While building package statistics-0.13.3.0 using: /home/work/.stack/setup-exe-cache/x86_64-linux/setup-Simple-Cabal-1.24.0.0-ghc-8.0.1 --builddir=.stack-work/dist/x86_64-linux/Cabal-1.24.0.0 build --ghc-options " -ddump-hi -ddump-to-file" Process exited with code: ExitFailure (-11) Logs have been written to: /home/work/server/dev/taiji/.stack-work/logs/statistics-0.13.3.0.log

我說：「隨機失敗」，因爲這可以通過重啓stack build固定。但以後再構建另一個軟件包時會失敗。

我看了看dmesg | tail，它說：

任何想法？

這原來是一個內存缺陷問題。
