I have implemented the support for the Delphi-compatible non-

I am ready to commit the improved (and fully compilable) version.
Per Jonas Maebe's suggestion, I am going to create a new branch

branch, I was consistently getting 500 Internal Server Error).
Do you already have an svn account?
begin
Foo().Bar()

end.

Does this indicate a problem in the compiler, or is this warning
bogus?
It indicates a problem in the compiler. As the message indicates, it
means that you (or someone else before you) are trying to free a temp
(allocated via tg.gettemp or the like) twice. The generated code will
still be ok in this case, but it could lead to trouble in case a temp
would be allocated again in between which would happen to get the same
address as the old one, since then the second free of the old temp
will free the new temp.
