Use the value of the first element as the initial value of the __valarray_sum accumulator. Value-initialization might not create the additive identity for the value type. Make a similar change to __valarray_product even though it's only ever used internally with a value_type of size_t. PR libstdc++/87641 * include/bits/valarray_array.h (__valarray_sum): Use first element to initialize accumulator instead of value-initializing it. (__valarray_product<_Tp>): Move to ... * src/c++98/valarray.cc (__valarray_product<_Tp>): Here. Use first element to initialize accumulator. (__valarray_product(const valarray<size_t>&)): Remove const_cast made unnecessary by LWG 389. * testsuite/26_numerics/valarray/87641.cc: New test. From-SVN: r265270 |
