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.
In lldb you can set breakpoints by typing either break or b followed by information on where you want the program to pause. After the b command, you can put either: a function name (e.g., b my_subroutine ) a line number (e.g., b 12 )
Type quit to exit the lldb session.
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. b
is a synthetic command that attempts to roughly recreate the gdb breakpoint syntax.
