Hi all,

The following leads to a consistent crash on my PC:

tbl =
 {{3.7372349521625203`, 7.8999536564180906`}, {-1.5683136806862397`,
   3.549628027104541`}, {-9.326537784015741`, -5.7268546790245844`},
{-6.8805945246545`, 6.849090400951159`}}

sp = Interpolation[tbl, Method -> "Spline"];

sp1[x_] = D[sp[x], x];

NIntegrate[sp1[x], {x, -9, 4}].

Same on yours?

Cheers -- Sjoerd
