H5Pget_filter2 takes cd_nelmts as the number of elements the cd_values buffer can hold and
writes up to that many. It was given sizeof(cd_values) = 32 for an 8-element array, so a
filter carrying more than 8 parameters would have been written past the end of the buffer.
Bitshuffle carries 5, so nothing overflowed in practice.
The "Weird value" message printed cd_values[1] while the test above it is on cd_values[4].
