 Replying to [comment:2 Algunenano]:
 > I can reproduce it in master using the instructions attached. It doesn't
 always happen, but creating and dropping the index several times leads to
 the crash eventually.

 It seems the bigger the table, the higher the chance it happens. I guess
 importing the dataset several times increase the chances, in case it is
 hard to reproduce.
