Hi dukeleto,
Its a bug in compiler with double literal constants code generation. As a workaround you can fisrt declare double literals and use them later in an expression-
kernel void sensor( double p_in[][], out double2 sigma<> )
{
double temp;
int4 outpos = instance();
int ipos = outpos.x ; // has slip in it
int jpos = outpos.y ; // has slip in it
double two = 2.0;
double one = 1.0;
temp = (-p_in[jpos+1][ipos] );
temp = temp + two*p_in[jpos][ipos];
sigma.x = temp;
sigma.y = one - temp;
}
