As stated above, this function appears to be of critical importance. If you are experiencing random hangs and crashes in your scripts, suspect a lack of fbsql_free_result(). It appears that failure to explicitly release a result set causes memory problems, usually manifested by Apache segfaulting. With FrontBase < 3.4, this caused us very serious problems as locks were not being released, resulting in a stalled database. With 3.5, this no longer happens, but nonetheless the httpd child dies, which means that pages are only partially output, and also impacts on performance. I don't know the internals of the fbsql PHP driver and don't have time to investigate further. Simply using fbsql_free_result() without knowing exactly what is causing the problem might look like voodoo, but in my experience it is voodoo that works.
