		mhorneUnsubmitted Not Done Inline Actions How can such an optional class appear in this list? It seems like it shouldn't happen, because you take care to call `pmc_mdep_alloc()` with the correct `nclasses` value. mhorne: How can such an optional class appear in this list? It seems like it shouldn't happen, because…
		rayAuthorUnsubmitted Done Inline Actions For example, one of classes fail to initialize. It have to be present in a list, otherwise class number and array position will not match. But to not process that class we can check number of counters it add (0 here). ray: For example, one of classes fail to initialize. It have to be present in a list, otherwise…
