sorry about the noise, it turns out i had two
delete GroundCallback;
in FGFDMExec::DeAllocate(void) (in src/FDM/JSBSim/FGFDMExec.cpp). it's
probably an artifact of the carrier patch. that aside, i guess it
would make sense to set the pointers to zero right after we delete
them so things like this won't happen again.
looking at FGFDMExec::DeAllocate(void) it also looks like there are
some pointers we are deleting without setting them to zero (even
later) (GroundCallback being one of them). maybe we can apply
something like this:
