Description

Fused binary (and maybe also unary) elementwise operations with a column vector as SideInput (e.g., b) do not replace the position %POS% with the respective row index, but with 0 instead.

I found this issue when generating a SpoofRowwise class including two different cbind operations. The first call to cbind has the correct position as parameter because it depends on the main input

double[] TMP38 = LibSpoofPrimitives.vectCbindWrite(a, TMP37, ai, len);

Whereas the second cbind depends on SideInputs and has a 0 as index parameter (aix)

double[] TMP40 = LibSpoofPrimitives.vectCbindWrite(b[0].values(rix), TMP39, 0, b[0].clen);
