By now I am almost certain that it is related to different compiler versions in *testing* and *stable*. I came to this conclusion based on the following findings. - If I build and install *atac* in *stable*, and then run it with some test data, it works fine. The same done in *testing* results in a segfault, mentioned in my previous letter; - After looking through the dependencies, I was able to eliminate the segfault on *testing* by installing an older version of gcc, the one that is used in *stable*. I am worried that I will not be able to identify the offending piece of code. Could you suggest how to proceed here? With regards, Liubov
