SQLITE_INTERNALFATALTier 3 — Handle with care⚠️ MEDIUM confidenceInternal logic error in SQLite
🔴 Production Risk Error
Critical — close and reopen the database; restart the process.
What this means
SQLITE_INTERNAL (2) indicates an internal consistency check failed within the SQLite library itself. This should never occur in a correctly compiled SQLite build and almost certainly indicates a bug in SQLite or severe memory corruption.
Why it happens
- 1Bug in the SQLite library itself.
- 2Memory corruption caused by another part of the application.
- 3Mismatched SQLite header and library versions.
How to reproduce
Extremely rare. May appear in fuzzing or if the SQLite amalgamation was compiled incorrectly.
# Not normally reproducible in user code
# If seen, file a bug at https://sqlite.org/forum/Fix 1
Why this works
Check that your SQLite shared library matches the header version (sqlite3_libversion()).
Fix 2
Why this works
Ensure no other thread or process is corrupting shared memory.
Fix 3
Why this works
Report the issue to the SQLite developers with a reproducible test case.
