+ * helper.c (create_casereader_from_data_store): New function.
+ (execute_syntax): Only replace the active file data by a new
+ casereader if syntax caused the active file to be read, to avoid
+ exponential slowdown as an increasing number of snippets that do
+ not read from the active file are consecutively executed. Bug
+ #20910. Reviewed by and heavily influenced by John Darrington.
