The problem is due to the use of an older API in type conversion. I
think I can provide a fix in a few minutes.
The compare function is type-specific and works for strings but requires
the same length string for each argument. It is defined as part of the
PyArray_Descr object (defined in arraytypes.inc.src).
It may be possible to not require contiguous arrays, but that is a
