The N option is irrelevant for profile histograms.
The overflow/underflow options are illegal for profile histograms because
insufficient information is stored to calculate the error bars.
None of the test options (S, C, or A) check on the number
of entries in a profile histogram bin.
(To do that, make a separate 1-dimensional histogram.)
This has an unexpected effect when the number of entries are small.
Bins with no entries always pass the S and C options
(no data is compatible with any distribution), so in such
cases more bins pass than called for by TOL.
