当我使用stack build构建程序包时，它在安装依赖程序包的过程中随机失败。以下是一个示例错误消息：
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
我说“随机失败”，因为这可以通过重启stack build来解决。但是以后建立另一个包将会失败。
我看了dmesg | tail，它说：

有什么想法吗？
答案 0 :(得分：0)
这证明是一个内存缺陷问题。
