Thanks for the pointer. Let me try again to explain why I object to the footnote: The footnote assumes that the reader will make the extrapolation that 1) since va_list is an object type, and 2) since array types are (also) object types, and 3) since array types in function arguments are converted to pointers, the actual type of a va_list object when declared as a function argument need not in fact be va_list but va_list*, despite the fact the declaration clearly appears to say otherwise. I am not a casual reader of the standard -- I read and interpret standards for a living. It seems that if I have trouble making that leap above it may not be so obvious to others either (as demonstrated by the lively discussion in the referenced bug). Perhaps removing the footnote is an unnecessarily drastic change. But clarifying it by mentioning the caveat above would, IMO, go a long way toward helping readers avoid the trap that I (and others) fell into. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20951
