The symptom of this testcase passing might work but the bug is still there and
most likely cannot expose it at the tree level and it is semi hard to expose it
even on the RTL level.
Comment #5 shows what needs to be added to the Fortran front-end which I will
do sometime this week when I get some time (but note I have two papers to write
which is what is right now taking up my time).
