[ADMB Users] How often is a re-compile needed?

[dave fournier]

Short answer is if in doubt recompile.

Longer answer is that you don't need to recompile if you are just adding a
non class member function.  However if you add a class member function 
it may change the
vtable entries so you should recompile. If you are adding a new field to 
a class you should recompile.

If you need to recompile and don't you will often get strange crashes. 
So if you experience
a strange crash recompile and get a coffee before you waste time 
thinking about it.
