I found that there is a bug in the latest version of movei and it seems based on page 130 of the book "the practice of programming" that it is a memory allocation error. I see different behaviour in debug configuration and in release configuration. I also saw different behaviour when I only added one printf. My question is what is the fastest way to detect the bug. I have a lot of arrays and adding a code to check if I wrote outside the allocated memory in every place is a lot of work. I think that it may be better if the compiler can do it for me(or maybe the compiler can do it and I do not know how it can do it). Is there a reason that prevent the compiler to check only in debug mode that what I put in the arrays make sense before putting the information in the arrays? Note that I save previous versions of movei and I may try to compare number of nodes in debug mode and release mode to try to find the latest version that has the bug but the problem is that I cannot know that I have not the bug from identical output and I can only know that I have a bug when the output is not identical.
