We found an assertion failed in sqlite. Here’s the POC:

INSERT INTO v0 VALUES ( 10 ) ;
SELECT * FROM v0 JOIN

Agreed. APIs between library boundaries generally need to be C. This is pretty

This is yet another fault not in SQLite itself, but in the auxiliary
VM register tracking logic that we use during testing and debugging.
Hence, it only comes up if you compile with -DSQLITE_DEBUG.
Indeed! Thanks Dr. Hipp and the rest of the team for such a wonderful, and
easy, and light, and robust, and... product.

Hi,
We found a debug assertion bug in sqlite. Here’s the PoC:
—
CREATE TABLE v0 ( v1 , v2 FLOAT ) ;

END;
INSERT INTO v0 ( v1 , v1 ) VALUES ( '' , 10 ) ,( '' , 0 ) ,( 'AIR' , 10 );
