"set optimizer_switch to e or d causes invalid memory writes/valgrind warnings": due to prefix support, the argument "e" was overwritten with its full value "engine_condition_pushdown", which caused a buffer overrun. This was wrong usage of find_type(); other wrong usages are fixed here too. Please start reading with the comment of typelib.c.
