Hmm, even without understanding Fortran it looks like
real(fgsl_double) :: ra, xa(10), ya(10), da(10), di(10), d(2)
declares d as a 2 element array, but
#0 gsl_poly_dd_taylor (c=0x7fffffffd930, xp=0, dd=0x7fffffffd980,
xa=0x7fffffffd8d0, size=3, w=0x7fffffffd9d0)
(gdb) p size
$16 = 3
For the moment I'll assume user error.
