Yes, even without any asymptote code, this breaks. But there seem to be
multiple problems. One is fix-empty-lines, a local routine defines
inside org-babel-asymptote-table-to-array: it seems to assume that the table
is a list of lists, whereas in this case it's a list of strings. The
following patch (which probably is wrong, in that it cures the symptom
rather than the disease):

lets things go a bit further, but there is mayhem in orgtbl-format-line,
which is called by orgtbl-format-section, which is called by
orgtbl-to-generic above, and I didn't go any further: I just don't know
what the preconditions are on these routines.
