Subject: [PATCH] Bug 697548: use the correct param list enumerator
When we encountered dictionary in a ref_param_list, we were using the enumerator
for the "parent" param_list, rather than the enumerator for the param_list
we just created for the dictionary. That parent was usually the stack
list enumerator, and caused a segfault.
Using the correct enumerator works better.
