Also worth getting into the habit of declaring a private copy constructor and operator = for classes that are not designed to be copied. This will cause a compile error for the sort of bug that bit you!

Is there a gcc compiler warning that would flag function call arguments

just spent way too much time debugging a problem where I inadvertently
called a function with an object, instead of the address of the object.
The default copy constructor did a shallow copy on entry to the
function. On exit, the destructor did a deep delete, removing the
entire tree that was being pointed to.


Talk about shooting myself in the foot!  :-(
