ruby-on-rails - 使用ctrl-n自动补全单词时，Vim随机出现段错误

Question

我正在使用mac osx随附的系统vim(7.2)(当前为10.6.7)。我主要使用rails.vim进行Rails开发。

随机地，当我尝试使用ctrl-n vim自动补全单词时，segfault会退出。任何想法是什么原因造成的？或关于如何开始调查造成这种情况的任何想法？我无法使它可靠地崩溃，但是它经常出现。

这是Mac控制台应用程序中显示的内容的简短片段

时间到

收集系统信息

ldd $(which vim)

uname -a

获取一个coredump(在Linux上，您可能需要执行ulimit -c unlimited)

或者，在调试器中运行vim

。

  gdb $(which vim)
  (gdb) break main
  (gdb) run file1.txt
  (gdb) break abort
  (gdb) break assert

(考虑其他要监视的东西)

收到断点/信号时:

  (gdb) bt
  (gdb) info threads
  (gdb) thread apply all bt

  (gdb) bt full
  (gdb) thread apply all bt full

将相关输出发送到vim错误列表(在vim中执行:he bugs以获取详细步骤)。

Of course, the output of the stack traces will greatly improve once you install the debug symbols with the packages for vim (and it's dependencies). I don't know how to do that on Macs, sry
