TF2::Integral problem

Hi rooties,

I am trying to use TF2::Integral and when the upper limit of integration is increased above a certain value I get the error

Warning in <TF2::Integral>: failed code=1, minpts=17, maxpts=10000, epsilon=1, nfnevl=9979, relerr=nan

The function does not present any singularity in the region on which I am trying to integrate.
It seems to me that what is causing problem is this element of the integrand

TMath::Power((var[0],(int)(var[1]))

the upper integration limit of var[1] is giving me problem. I have tried to increase the accuracy up to 1 without any effect. The code I have produced is standalone (not a macro).
Any suggestion?

Thanks

Luca
