--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> ---
The testcase of comment 2 seems to be the same as the one of
bug 106449 comment 4, which went in as

r13-1887-g97d32048c04e97  openmp: Fix up handling of non-rectangular simd l=
oops
with pointer type iterators [PR106449]

A slightly modified variant of that testcase went in follow-up commit

r13-1893-g85fe7e7dd1f146  Add libgomp.c-c++-common/pr106449-2.c

* * *

>From the bug comments, it seems as if the following remains:

"Non-rectangular loops with class random access iterators remain broken, th=
at
is something to be fixed incrementally."

* * *

However, given the commit for PR106449 (see above) and the earlier commit
r12-4733-g2084b5f42a4432  openmp: Allow non-rectangular loops with pointer
iterators
(committed right after the commit of comment 3):

I wonder whether the only thing that remains to be done is to add a real C++
testcase for random access iterator non-rect loops - assuming that the poin=
ter
patches cover all what's needed in terms of compiler support.=
