<pre>I went and looked at sys/socket.h, and it uses transparent unions. After
reading the gcc docs
(<a href="https://gcc.gnu.org/onlinedocs/gcc/Type-Attributes.html#index-g_t_0040code_007btransparent_005funion_007d-attribute-3157">https://gcc.gnu.org/onlinedocs/gcc/Type-Attributes.html#index-g_t_0040code_007btransparent_005funion_007d-attribute-3157</a>),
we decided this was a bug in clang. transparent union changes how the value is
passed.
Turns out, we had a test case with a FIXME already documenting the problem. I
fixed it in r222074.</pre>
