As I see from night build results, that Intel C++ 10.0 and acc 6.13 also failed to compile: http://people.apache.org/~sebor/stdcxx/results/linux_suse-9.1-amd64-icc- 32b-10.0-15s-559650-log.gz.txt http://people.apache.org/~sebor/stdcxx/results/linux_suse-9.1-amd64-icc- 64b-10.0-8S-559650-log.gz.txt http://people.apache.org/~sebor/stdcxx/results/hpux-11.23-ia64-acc-64b-6 .13-8S-559650-log.gz.txt The test instantiating valarray<UserClass>::operator{+-/*}= (...) operators, but they can't be instantiated because of UserClass has not provided +,-,/,* operations. >From standard: 26.5.2.6 valarray computed assignment [valarray.cassign] valarray<T>& operator*= (const valarray<T>&); valarray<T>& operator/= (const valarray<T>&); valarray<T>& operator%= (const valarray<T>&); valarray<T>& operator+= (const valarray<T>&); valarray<T>& operator-= (const valarray<T>&); valarray<T>& operator^= (const valarray<T>&); valarray<T>& operator&= (const valarray<T>&); valarray<T>& operator|= (const valarray<T>&); valarray<T>& operator<<=(const valarray<T>&); valarray<T>& operator>>=(const valarray<T>&); 1 Each of these operators may only be instantiated for a type T to which the indicated operator can be applied. Each of these operators performs the indicated operation on each of its elements and the corresponding element of the argument array. Farid.
