The first time I saw the failure was with
17d0982f425dbdeb528b70d141e70b006f6b9df6, r15-1423-g17d0982f425dbd
But that is not the source. Just before that were several changes to the
diagnostician code by David Malcolm.
524cdf4dab610e6e53b3b033eacbdb1a03687cc7
c371d7bdbe69201b4c91179ff6f3e2237e0e7fbe
bdcfe7f7f50ec64b45581a175d1eca41c74a3dfe
and more which may be the source.
As this is intermittent I have not been able to trace it exactly to a specific
change.
