+	- expr_streval: if after a call to get_array_value (which can call
+	  the expression evaluator recursively) we discover that expr_depth
+	  is less than it was before we called it, we assume there has been
+	  some kind of error and an expr_unwind, so we treat it as an
+	  error and either longjmp back to the expression top level or return
+	  0 immediately. Fixes bug reported by Eduardo Bustamante
