(Using OSX 10.10.1, XCode 6.1.1 6A2008a, lldb-320.4.156, Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn) )
Hi all, I have just started using LLDB and its Python scripting interface. I may have stumbled upon a deep bug related to null pointer treatment. http://lldb.llvm.org/scripting.html I tried to follow this scripting tutorial. http://pastebin.com/S0RhVG3s This is the output of my interaction with the lldb and the python script. (I haven't modified any part of the example code there) It seems like `if left_child_ptr.GetValue() == None:` expression (and other similar expressions) doesn't evaluate to true for null pointers I was able to cook up a python check for null pointer: def IsNullPtr(ptr): ptr_string = str(ptr.GetValue()) if re.search('[1-9a-fA-F]', ptr_string): return False; else: return True; I discussed this on the irc channel and zturner thought it looked like a bug and that I should post it here. Hope this helps. Please let me know if there is a standard way to do null pointer check through the python API. Especially a check for nullptr shared_ptrs.
