在emacs（使用gud）调试通常会导致堆栈溢出错误 [英] Debugging in emacs (with gud) often results in stack overflow error

问题描述

我正在调试emacs时收到此消息：

I'm getting this message in emacs when debugging:

error in process filter: gdb-stack-list-locals-handler: Stack overflow in regexp matcher
error in process filter: Stack overflow in regexp matcher

然后我必须杀死gdb并重新启动调试会话。

I then have to kill gdb and restart the debugging session.

任何想法？

推荐答案

嗯，我可以告诉你，这可能是由于一个正则表达式试图运行在一条长线上。 Emacs的正则​​表达式实现是...缺乏的。您可以执行一个 Mx toggle-debug-on-error 并获取堆栈跟踪 - 遵循这些文件可能会引导您使用regexp的罪魁祸首。

Well, I can tell you that this is probably due to a regexp trying to be run over a long line. Emacs' regexp implementation is ... kinda lacking. You can do a M-x toggle-debug-on-error and get a stack trace -- following the files there will likely lead you to the regexp culprit.

到目前为止，我还不知道。如果你发现，让我知道;）

As far as working around it goes, I really don't know yet. If you find out, let me know ;)
