saugustine added a comment.
I don't think this necessarily matters or is a reason to revert, but we are
seeing issues with this patch and swig 3.0.2, that disappear with swig 4.0.
The docs claim that versions past 3.0 are supported (except for some odd corner
cases).
The failure is:
Traceback (most recent call last):

If I modify the line
launch_info = lldb.SBLaunchInfo(None)
to
launch_info = lldb.SBLaunchInfo("")
I get this error, which gives a clue to the fix:
NotImplementedError: Wrong number or type of arguments for overloaded
function 'new_SBLaunchInfo'.
Possible C/C++ prototypes are:
lldb::SBLaunchInfo::SBLaunchInfo(char const **)
lldb::SBLaunchInfo::SBLaunchInfo(lldb::SBLaunchInfo const &)
So if I use a vector of strings to match the first overload, the error
disappears and the tests pass:
launch_info = lldb.SBLaunchInfo(["", ""])
Not sure the best way forward here. Either to abandon old versions of swig, or
to clean up the launch command.
