12 years agoI get the feeling something else is changing, or your timing specs are not good enough. Adding comments to the source code will probably affect the fit seed, which can change the layout, hence why you need good timing specs to reign in any problems.
If your design has flakey build characteristics (ie. some builds work better than others with minimal source code changes.), there is probably a problem with the design.
