clspv does not really support kernels calling other kernels.
In many cases it works because the called kernel got inlined at some point.
A quick work-around would be to compile with --inline-entry-points.
A good fix would be to have a wrapper for each kernel so that we always have a version with the spirv interface and one callable one.
