Control: tags -1 pending (fixed in Salsa, as far as I consider it my bug)
It looks like both of these originate further down the stack, not in libgpuarray:
The *ger error code is an OpenCL compile failure from inside clblast, so likely either pocl or clblast.
The *gemv problem appears to be that the definition of gemv is y=alpha*A.dot(x)+beta*y, the spec allows and possibly requires the second term to be skipped entirely if beta is 0, clblas does this but clblast doesn't, and libgpuarray pygpu has a short form for beta=0 that uses an uninitialized (i.e. potentially NaN) y. As a workaround I am changing this to a zero y, but it maybe should be fixed in clblast.
