--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think C11 and C90/C99 have a different idea here.  There is a relative
sequence point between the function call fn2 and the 0 but there is no sequence
point between the two assignments I think.

Sequence points are not my area of expertise so I could be wrong but I do know
that C11/C++11 does get rid of the idea of sequence points and change the name
of it to something else.
