When trying it on my new Mint installation, I even got a Segfault. This needs more work then just a small patch and I will let you know the progress as soon as possible.

Thank you for posting this issue here!

Bram,

Thanks for looking into this.

Could you also subscribe to Debian bug reports for faster turn around? You can do that from bottom left hand corner of http://packages.qa.debian.org/c/ccbuild.html

Release 2.0.3 fixes the shadowing problems. I still have to check out possible compilation errors when using extra security measures with g++-4.7
