I don't know. We are definitely implementing the ISO C++ Standard, and, by the way, many details in Stroustrup' books, predating the Standard, are know to be slightly different. I will also add that valarray is *very* special - its design was motivated by considerations of highest performance on superscalar architectures, etc. - for example vector::resize behaves in a completely different way, which probably you like better. > The application will be changed to avoid the loss of data on a resize of > arrays, which is a better idea anyway. Thanks for the speedy reply. For portability, that is the safe thing to do, yes, I agree. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29688
