I think this is because the revised (core-dumping) 'seq' is calling
vasnprintf with the equivalent of printf ("%.1Lf", 0.8L), whereas due
to the strange compiler settings on FreeBSD the original
(non-core-dumping) 'seq' called vasnprintf with the equivalent of
printf ("%.1Lf", (long double) (double) 0.8L).

I guess that the bug lies in the printing of a long double value that
is not exactly representable as a double.
