I do not have an intuition about it. I mainly compile with different 
compilers/libc to see whether it breaks or whether warnings are 
generated. When it compiles without warnings, I push and let others test 
it :)

Actually, sometimes it looks like I have been doing just that, but the 
worst is that I did try to test (most of the times).
