 As far as I can tell, this code is simply an optimization for generics that are instantiated with 
 value type arguments. Deleting the code seems to cause no ill effects, and the removal of this 
 code also happens to fix the problems described above.
 
 I plan to dig in to this optimization to determine if I can correct it, but in the meantime, it 
 would probably be wise to remove it.

+The if block that starts at line 6453 seems to be the culprit.
+
+If the stack is not empty, then it is emptied. However, if items were already on the stack 
+because they were going to be used later, they get hosed.
+
+Removing line 6454 (sp = stack_start;) seems to fix my problem, but I have no idea if it will 
+break any other cases, given that there is nothing to document *why* the stack needs to be 
+cleared.
