Clang found three instances of uninitialized use of nparams in the cleanup path. Unfortunately, one is a false positive: clang couldn't see that ret->params.params_val is guaranteed to be NULL unless allocated within a function, and that nparams is guaranteed to be assigned prior to the allocation; hoisting the assignment to nparams to be earlier in the function shuts up that false positive. But two of the reports also happened to highlight a real bug - the error path can dereference NULL.
