What steps will reproduce the bug?

There are some inconsistencies in how the sqlite3_reset API is checked.
All places where it is called via StatementSync::ResetStatement() are checked. For example:

node/src/node_sqlite.cc

Lines 3092 to 3093 in bf7e79c

	int r = stmt->ResetStatement();
	CHECK_ERROR_OR_THROW(env->isolate(), stmt->db_.get(), r, SQLITE_OK, void());

or some others not via ResetStatement():

node/src/node_sqlite.cc

Lines 3353 to 3354 in bf7e79c

	int r = sqlite3_reset(stmt->statement_);
	CHECK_ERROR_OR_THROW(env->isolate(), stmt->db_.get(), r, SQLITE_OK, void());

etc...

However, the following locations are not checked and should probably get exception checking as well:

node/src/node_sqlite.cc

Line 2972 in bf7e79c

auto reset = OnScopeLeave([&]() { sqlite3_reset(stmt); });

node/src/node_sqlite.cc

Line 3026 in bf7e79c

auto reset = OnScopeLeave([&]() { sqlite3_reset(stmt->statement_); });

node/src/node_sqlite.cc

Line 3473 in bf7e79c

auto reset = OnScopeLeave([&]() { sqlite3_reset(stmt->statement_); });

node/src/node_sqlite.cc

Line 3705 in bf7e79c

sqlite3_reset(iter->stmt_->statement_);

node/src/node_sqlite.cc

Line 3757 in bf7e79c

sqlite3_reset(iter->stmt_->statement_);

Similarly, sqlite3_step() is normally checked for errors, but not here:

node/src/node_sqlite.cc

Line 2896 in bf7e79c

sqlite3_step(stmt);

I could provide patches if this is a confirmed bug and the fix is desired.

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

Only reproduces if there's an internal libsqlite3 failure.

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

I would expect consistent checking and throwing of exceptions.

What do you see instead?

Failure is ignored silently.

This was detected with the help of a static-dynamic hybrid analyzer I'm developing.
