Did a run on 5.6 without my change. The output is

[root@debug010000002015 radix-tree]# ./main
random seed 1585904186
running tests
XArray: 21151201 of 21151201 tests passed
vvv Ignore these warnings
assertion failed at idr.c:269
assertion failed at idr.c:206
^^^ Warnings over
IDA: 34980531 of 34980531 tests passed
tests completed

Is these two assertion expected?
