Hi,
We found an assertion failed in sqlite. And this assertion seems not to be
fixed completely. Here’s the POC:
—
CREATE TABLE v0 ( v1 ) ;
INSERT INTO v0 ( v1 ) VALUES ( 10 ) ,( 10 ) ;
UPDATE v0 SET v1 = ( SELECT coalesce ( quote ( NULL ) , quote ( v1 ) , ( SELECT
1 FROM v0 AS v WHERE ( SELECT

This exists
Also spaghetti inheritance is a thing.

And I’ve spent too much time lately trying to figure out or debug
hellacious C++ spaghetti code
Someone who writes bad C, will write even worse C++

Thanks for adding these functions! My test generator/fuzzer is written in
Java and uses the JDBC interface. In order to call the C function, I would
probably need to modify the driver code or use JNI, which would both be a
bit hacky. Is there a compile-time option that can be set to provide

Thanks!
Fuzzers and testers:
I've created some new built-in SQL functions for SQLite that provide
direct access to some of the internal code-generator routines that
have historically given trouble:
expr_compare(A,B)
This function returns non-zero if expressions A and B are different.
