Any specific reason to use lsqlite3complete? If I understand
correctly, you're running two different versions of SQLite on the same
process (3.27.2 from C++ and 3.24 from lsqlite3complete).
Even if SQLite has very high forward file compatiblity between
versions, there's no guarantee that you can go forward and backwards
repeatedly and during an open transaction. It's probably worse when
they share the same process and thus might share file descriptors,
signals, and other kernel interface entities.
Much safer would be to use the same SQLite library for both C++ and
Lua. I'm no expert on Android packaging, but in most cases there's a
way to make it simply visible to lsqlite3. If you're using shared
libraries, it might just work. If you're compiling statically, some
linker flags could keep the SQLite symbols exported.
