BUG: assert_index_equal defaults to check_exact_index=False on integers

Sorry but I don't understand what the bug is from the title, looking at assert_index_equal's parameters I can see that check_exact always defaults to True
Looking at the comment, maybe you meant that check_exact_index in assert_series_equal defaults to False for integers?

Yes - thanks.
