opened on Aug 8, 2026

Version

v27.0.0-pre (main @ e2d7b34); reproduces on any build containing 8fc7341

Platform

Darwin 25.6.0 arm64

Subsystem

sqlite

What steps will reproduce the bug?

const{ DatabaseSync }=require('node:sqlite');constdb=newDatabaseSync(':memory:');conststore=db.createTagStore();store.run`-- comment`;

How often does it reproduce? Is there a required condition?

Always. All four query methods crash: run, get, all, and iterate.

What is the expected behavior? Why is that the expected behavior?

A thrown error, like the equivalent non-tag-store path produces:

db.prepare('-- comment').run();// throws: statement has been finalized

What do you see instead?

A segfault:

* thread #1, stop reason = EXC_BAD_ACCESS (code=1, address=0x0)
frame #0: sqlite3_clear_bindings(pStmt=0x0000000000000000) at sqlite3.c:93850
frame #1: node::sqlite::SQLTagStore::ResetAndBindStatement(...) at node_sqlite.cc:3442
frame #2: node::sqlite::SQLTagStore::Run(...) at node_sqlite.cc:3477

Additional information

The crash appears to have been introduced by #65041.
