If I am not mistaken Delphi doesn't guarantee this either. I remember I 
"learned it by doing" quite some time ago and I don't think I used FPC 
at that point, so it must have been Delphi.

A quick Google search revealed https://stackoverflow.com/a/11010685 - 
yes, when I run the code from the answer in Delphi 32bit the right 
"SideEffect(2)" call is executed before the left "SideEffect(1)" call.
