<pre>Undefined behaviour like this frequently results in unexpected outcomes.
If you really want less aggressive optimizations in this case then there's a
-fno-strict-return option that will help, though it doesn't cover all cases for
some pretty good reasons (see <a href="https://reviews.llvm.org/D27163">https://reviews.llvm.org/D27163</a>).
But fixing warnings is probably the best plan.</pre>
