I am tracking a crash when selecting the c172p. Not sure it is related to the
other crash already seen, but anyway :
In JSBSim.cxx, line 147 :
fdmex = new FGFDMExec( (FGPropertyManager*)globals->get_props() );
in FGFDMExec.cpp, line 99:
FGFDMExec::FGFDMExec(FGPropertyManager* root) : Root(root)
in FGFDMExec.cpp, line 199:
delete Root;
So one can see that FGFDMExec.cpp is deleting the global property tree, that is
a smart pointer, not a real pointer by the way !!!!!
Of course, it crash at the next use of the property tree.
$ git log src/FDM/JSBSim/FGFDMExec.cpp

Sync with JSBSim cvs + Anders' patch to get it working with FlightGear.
