No preprocessed source for 6 months.
There's no way we can reproduce the bug without it.
If you can attach the preprocessed source, please feel free to reopen the PR.

While trying to make GCC remove some sign extensions in some code I got an RTL

gcc-4.3-20071221 on an AMD64 FreeBSD system (no cross compilation).
