LLDB:通过控制台为malloc_error_break设置断点 [英] LLDB: Setting a breakpoint for malloc_error_break through the console

问题描述

我在代码中遇到了一些与malloc相关的问题:

I'm running into some malloc-related issues in my code:

malloc: *** error for object 0x103401e28: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug

我已经尝试过类似的事情:

I've tried things like:

(lldb) breakpoint set malloc_error_break
error: invalid combination of options for the given command

如何使用终端设置此断点?我在网上搜索过，仅发现涉及Xcode的结果.

How do I set this breakpoint using the terminal? I've searched online and only found results involving Xcode.

推荐答案

如果您熟悉gdb，则此小技巧可能会有所帮助:

If you are familiar with gdb, then this little cheat-sheet might help:

也:

(lldb) help break set

将为您提供有关在lldb中设置断点的许多信息.

will give you lots of information about setting breakpoints in lldb.

在这种情况下:

(lldb) br set --name malloc_error_break
(lldb) br set -n malloc_error_break

或:

(lldb) b malloc_error_break

第一个示例使用breakpoint set，这是一个"true"的lldb命令-它使用标志选项&值来区分您要尝试做的事情. b是一个合成命令，试图粗略地重新创建gdb断点语法.

The first examples use breakpoint set which is a "true" lldb command - it uses flag options & values to distinguish the kinds of things you are trying to do. bis a synthetic command that attempts to roughly recreate the gdb breakpoint syntax.
