--- Comment #5 from Avi Kivity <avi at scylladb dot com> --- We hit the system header warning suppression problem again, in a different context. std::exclusive_scan(ptr-to-64bit-int, ptr-to-64bit-int, 0, std::plus()) uses a 32-bit accumulator, taking the type from the third parameter. -Wconversion would have caught this if enabled, but since the warning is suppressed, even that doesn't help.
