There's a similar bug involving LTO; consider the following:
a.cpp:
using size_t = decltype(sizeof(0));
void *operator new(size_t) __attribute__((alias("something")));
b.cpp:
int *pr16715 = new int;
If I link these two together with llvm-link, I get exactly the same error.
Overall, this seems like a very fragile constraint; maybe we can relax
it somehow?
