Looking at the stack trace, this seems like a duplicate.  However, I don't have access to the reproducer testcase in order to confirm that.

Thank you very much for looking into this quickly, Richard! I've attached the test case.

My guess matches everyone else's here -- I think this is Issue 922399.

Unable to repro, even after lowering RLIMIT_STACK to 250000.  What is the stack size limit for your testing infrastructure?

Were you running dbfuzz2, by any chance?

I was able to repro with our SQLite build (with and without pending backports). This test case is against sqlite3_fts3_lpm_fuzzer, which (AFAIK) currently only exists in the Chromium tree.

Oh, this is probably because I attached the raw test case, and confused you. Sorry about that!

Here are the SQL statements ran by the fuzzer.

I can now recreate the problem.  It appears that the issue was fixed by check-in https://sqlite.org/src/info/da587d18575ac06a

I'm going to take the bullet and backport this, so we stop bothering you with clusterfuzz reports for the same problem.
