In my case the duplicated section is related to guard variable of a static
function variable.

I haven't been able to reduce this to a small test case, because being
something related to optimization it's being very sensitive to the actual code
being compiled. My code is located on github:

wget
https://github.com/pisto/spaghettimod/archive/4342b93933ce8d9f18c1bc2cc35db3e689a6d101.zip
-O spaghetti.zip
unzip spaghetti.zip
rm spaghetti.zip
cd spaghetti*
make PLATFORM=x86_64-w64-mingw32

(you'll need a working `pkg-config lua`).
