The type argument to sizeof could have the wrong type. The expression argument to sizeof could be missing the *. Unpleasant consequences are possible in both cases. Probably each maintainer has a style they prefer. Perhaps it could be useful to adjust the code to follow the dominant strategy, in cases where there are a inconsistencies. For example if (...) x = foo1(sizeof(struct xtype)); else x = foo2(sizeof(*x)); might at least cause some unnecessary mental effort to process. julia
