Fredrik (the Anonymous Poster) has identified some differences with the calling conventions on Linux, mainly how classes are returned from functions. It seems that all classes, independent of size and complexity are returned in memory by GCC on Linux. I believe we have been able to correct these problems already, and the fixes will be available with 2.0.0 WIP 3.

I will try to migrate as much as possible of these corrections to AS 1.10.1 as well, though some might not be possible, or require too much work.
