Generated with:

const char* kName2 = "the second key";

ASSERT_EQ(net::OK, OpenEntry(kName2, &entry));
Set a breakpoint on that last line, and when the entry is moved from one list to another, crash the process:
rankings_->Remove(entry->rankings(), Rankings::NO_USE);
rankings_->Insert(entry->rankings(), false, Rankings::LOW_USE);
entry->entry()->Store(); <---- crash here
