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
I've tried things like:
(lldb) breakpoint set malloc_error_break
error: invalid combination of options for the given command
How do I set this breakpoint using the terminal? I've searched online and only found results involving Xcode.

If you are familiar with gdb, then this little cheat-sheet might help:
http://lldb.llvm.org/lldb-gdb.html
Also:
(lldb) help break set
will give you lots of information about setting breakpoints in lldb.
In this case:
(lldb) br set --name malloc_error_break
(lldb) br set -n malloc_error_break
or:
(lldb) b malloc_error_break
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.
