Fixed code that caused a seg-fault after parsing a (deferred) post-count argument followed by a (nested) function-call argument.
...
The old broken code defers the count until the end of the (parent function's) argument list. But, a nested function call clears the pointer to the deferred type. That leads to an access violation.
The new code defers only until the end of each argument. Fixes #1320 .
