Hmm, can't reproduce with x86_64 compiler with -m32:

Without hwy dependency:
% more Makefile bytes.cc demo.cc
::

::
CXXFLAGS := -O2
demo: demo.o bytes.o
$(CXX) $(CXXFLAGS) -o $@ $^
clean:
rm -f bytes.o

Brushed-up example (with Makefile):

Simplified version:

#include "hwy/tests/test_util-inl.h"
struct TestMulHigh {

void operator()(T /*unused*/, D d) {
