Hmm odd, it seems as the weak_ptr mOwner is returning an empty
shared_ptr when calling mOwner.lock().....
#7 unity::MT::GrabHandle::requestMovement (this=0xacf2c78, x=779, y=447,
button=1) at
/build/buildd/unity-6.4.0/plugins/unity-mt-grab-handles/src/unity-mt-grab-handle.cpp:39
ghg = {px = 0x0, pn = {pi_ = 0x0}}
I wonder if a check should be there to skip over using the ptr if the
.lock() returns an empty shared_ptr
Though it would be best to figure out why the weak_ptr expired....
I haven't been able to reproduce this though...Ill see if I can
reproduce it...
