OK, here's a stab at decoding.  Better guesses, welcome

This is std::function, which stores a bound function call.  It is a bound
function call to a POINT_EDITOR class function that takes a TOOL_EVENT as a
parameter and returns an int.  It is 16 bytes inside the function, so
second instruction.  My guess would be removeCorner was called and
m_editPoints is NULL.

It's odd that the user reports trying to move a component when this
triggered.
