Danny is correct. C++ objects have global overhead and therefore can't be
used in apps when they are sub-launced w/ launch codes.

I don't know C++ but I'll venture a guess since no one else has answered.
I'd guess that it requires access to globals for some reason - perhaps to
access the vtable? You don't have access to globals when you receive this
launch code without sysAppLaunchFlagSubCall. The precise conditions under
which you do have access to globals is a little hard to figure out, but it's
approximately:
normal launch
goto (with or without new globals)
find (sub-launch only - but sub-launch flag isn't set on Mac
simulator and it should be)
others (sub-launch only)
If your app is multi-segment, these are the same conditions which determine
what code has to be in the first segment.
