We don't test SQLite in MacOS 10.4, but we do test every release on MacOS
10.2.  For that platform, we add the compile-time option:

    -DSQLITE_WITHOUT_ZONEMALLOC

Doing the same should clear the problem on MacOS 10.4 as well.  And using
that approach will save us from having to maintain a bunch of hard-to-test
preprocessor logic.
