This fixes a 'for' loop in std::piecewise_linear_distribution that increments two iterators with a comma operator between them, making it vulnerable to evil overloads of the comma operator. It also changes a 'for' loop used by some other distributions, even though those are only used with std::vector<double>::iterator and so won't find any overloaded commas. libstdc++-v3/ChangeLog: PR libstdc++/122062 * include/bits/random.tcc (__detail::__normalize): Use void cast for operands of comma operator. (piecewise_linear_distribution): Likewise. * testsuite/26_numerics/random/piecewise_linear_distribution/cons/122062.cc: New test.
