Yes. A NULL return from sqlite3Malloc() is an error condition meaning that you have run out of memory. That is very different from returning a zero-length memory allocation. You wouldn't want to substitute a NULL for an empty string in SQL would you? Having sqlite3Malloc return NULL for a zero-length allocation is roughly the same thing. -- D.
