AVR-Chat

I would check the project's optimisation settings. If your project is highly optimised, timings and similar type of problems may occur depending on the types of optimisations. I would try to remove all optimisations to start with to see if it all works as expected first.

I had a similar problem where no apparent changes appeared in the code except a few mild optimisations and the whole code went haywire. Innocent looking optimisations can cause a lot of headaches.
