Comment:
In 3.2.2.alpha0 this works fine as long as the matrix has 0 rows and 0
columns, but for 0 rows and a nonzero number of columns (or vice versa) we
still get the error. This arises from the fact that Pari doesn't have the
notion of a matrix with 0 rows and 1 column, so the matrix gets
"truncated" (!) before being passed to Pari.
I will fix this as part of #4681.
