 This assumption is incorrect (for my case), so all derived possible

The details will of course be different because your code is different (you didn't show it, so all anyone can do is guess).  But the type of effects I described, and the way to get good information about your code and how it works, is valid for a wide range of code.  The fact that you think C does not have checks, and that you dislike that your erroneous code compiles and runs without you being informed of the errors, shows that you could benefit from the kind of suggestions I gave about good tool usage.
Understanding how to get the best from your tools is as important a part of software development as understanding the details of the language you are using.  You'd learn more about both if you didn't skip and snip useful help.
