The workaround of Comment 5 stopped working for my actual use-case some time
ago. Now I do this:
```C++
export constexpr void expects(bool truth) noexcept {
if (not truth) std::terminate();

I can make it fails with sanitize=address:
/usr/bin/g++-12 -DHWY_STATIC_DEFINE
-I"/home/malat/highway-0.17.1~git20220711.f0a396a" -O2 -fsanitize=address -fPIE

Using `-fno-strict-aliasing` causes the same symptoms:
/usr/bin/g++-12 -DHWY_STATIC_DEFINE

Compilation line for -save-temps is:

I can reduce the gtest code to simply:
```
HWY_NOINLINE void TestAllMulHigh() {
ForPartialVectors test;
test(int16_t());
// test(uint16_t());
}
```
