Description Nicholas Nethercote [:njn] 2012-05-31 17:45:37 PDT
Bug 710922 was caused by calling all() on a hash table that hadn't had init() called on it.  A |JS_ASSERT(initialized())| assertion inside all() would have caught it immediately.  There are probably other places where that assertion would also be helpful.

This patch adds JS_ASSERT(table) to two sets of HashTable methods.  

- The first set definitely need it: findFreeEntry(), add(), two versions of
  remove(), all().

- The second set don't need it, but it seems like a good idea just to
  encourage people to init() their HashTables immediately:  empty(), 
  count(), capacity(), generation, sizeOf{In,Ex}cludingThis().
