So use the 10.05.
Code::Blocks is a free software. The goal of a free software programmer is to improve the software itself, not to provide a safe way to install it for you. It should request a too huge effort to test all possible configurations. If your priority is the safety of your environment, use the 10.05 version, or use another soft.
At least you could try with a sandbox, if you absolutely want a new feature which isn't present in the 10.05 release. But that's at your own risk.
