The error is pointing towards this line.
key = 10;
|
val[0] = 20;
|
val[1] = 30;
|
for (i = 0; i < 100000; ++i) { |
key += i;
|
val[0] += i;
|
val[1] += i;
|
cursor1->set_key(cursor1, &k);
|
cursor1->set_value(cursor1, &v);
|
testutil_check(cursor1->insert(cursor1));

}

Seems that the variable key is getting an integer overflow. Verify with UBSAN build again once fixed.
