I found an assertion failure while SQLite (latest, 92ade220dcf5c1b7) executes the following queries.

Here is the link to file malform used for reproducing the crash: malform

PRAGMA hard_heap_limit=800000;
.m cs
.i malform 0

Here are the outputs:

sqlite3-asan: shell.c:23154: char *zAutoColumn(const char *, sqlite3 **, char **): Assertion `rc==SQLITE_DONE' failed.

My compilation flags:

export CFLAGS="-g -DSQLITE_DEBUG
            -DSQLITE_ENABLE_TREETRACE
            -DSQLITE_ENABLE_WHERETRACE
