handling errors in the implementation

[chrisosaurus]

Looking at the implementation for obj_new we see

Obj *obj_new(char tag) {                                                                                                                                                                                          
  Obj *o = malloc(sizeof(Obj));                                                                                                                                                                                   
  o->prev = obj_latest;                                                                                                                                                                                           
  o->alive = false;

a call to malloc can fail

I would like to add some error handling here, if that suits you.

How would you like errors of this nature to be handled?
I am happy to just print error and exit the program (probably something stronger than an assert - as asserts can be compiled out).

There is an ettor handling mechanism, you can see it used in primops.c a lot. The macros used for error handling are in assertions.h. They allocate themselves though so maybe better to exit, like you say.

Please go ahead and add the code if you feel like it!
