Interesting. The patch looks fine, I'm wondering if people made a
clang bug report about this behavior with structure assignments?

Even if most other projects likely don't have issues with stack size,
it looks very non-optimal from a performance standpoint too to create
a pointless temporary copy on the stack.

I assume - but didn't check - that gcc didn't do the same stupid thing
for that code?
