<p>But that seems orthogonal to your point. Your hypo seems to be
that the compiler is under this license ("infringes the
copyright of the compiler") and the question is about the
relationship of the output to the compiler. You dismiss the
possibility that some copyrightable portions of the compiler end
up in the compiled code, but I understand that it is possible -
libraries, for example. So it's at least theoretically possible
that the output could be a derivative work of the compiler, and
if so, this is a quasi-copyleft requirement (more about that in
a moment), which is acceptable for an open source license. </p>

<p>A great example of this is the run time exception in the GCC:
