<pre>This bug has been in my code and passed everything, -Werror -Wall and running
with asan.
<a href="https://gcc.godbolt.org/z/CSC4ra">https://gcc.godbolt.org/z/CSC4ra</a>
Misplacing two parameters in a vector constructor is very common.
On Mac asan doesn't catch this (on linux it does - this is how this bug was
found, but a couple of month later)
I wondered if this is possible to warn on, given that it's very similar to
signed/unsigned casts.
Clang version: Apple clang version 11.0.0 (clang-1100.0.33.8)</pre>
