integral types
summary
Shows concrete failures: a template in Boost property_tree bug truncates wide characters to 8 bits and misparses hex character references; Boost.Accumulators overflow silently corrupts sum and mean when integers overflow because the author assumed it "can't happen"; std::lcm documents a precondition that leads to undefined behavior when a product exceeds the type; demonstrates branch-free overflow detection algorithms that compile to ~3–4 x86 instructions versus 7–10, and argues for checked arithmetic primitives in the standard library and portable multiword ops.
