Given that I have an "acceptable" source code of some program (Tor was mentioned in a previous version of this question), where "acceptable" means that I trust this source code and want to use it for my needs; is there a possibility, that if I use pre-complied binaries (someone else's compilation), that I will get an "unacceptable" binary that contains different code than the "acceptable" source code I saw (e.g. backdoored binary)?
