return 0;
else
return a;
}
```
Still need: `-fdisable-tree-fre1` though because fre is able to

I've got a C++ reduced test-case:
$ cat x.ii
template struct is_same;
template using enable_if_t = _Tp;

Both -O1 and -fno-strict-aliasing remove the bug:
$ g++-14 unit-t.cpp -O2 -Ijson/include -o a -O1 && ./a
SUCCESS!
$ g++-14 unit-t.cpp -O2 -Ijson/include -o a -fno-strict-aliasing && ./a
