I believe that the problem is that in your compile the 'pid_t' param to
AttachToProcessWithID() is being passed as an 'int'.
10.13 OSX will only accept a uint64 version of pid. So the variable
being passed to AttachToProcessWithID() needs to be declared as
lldb::pid_t instead of just plain 'pid_t'. lldb::pid_t is the desired
64 bit version of the PID.

is there anything I can do to correct this error right now? I have the same problem
samdup123 commented
I actually just fixed it, ill make a PR
arifogel commented
Thanks @samdup123!
So how did the break happen? Did LLVM change their API, or does it have something to do with OSX APIs (independent of LLVM)?
