See Haral
Hi Patrick,
I did not see any similar report in bugzilla, so could you please
open a PR and attach a self-contained reproducer? Ideally the
reproducer would be reduced to simplify the analysis for those
familiar with the status of the OpenACC implementation.
Thanks,
Harald

Hi Harald
as I said, it is a large, massively parallel fortran code: more than 700
files, some with several thousands of lines. It could be difficult to
create a small reproducer but I will try if the problem is not known as
an other git branch of this code also create an internal error on
an
Cc:ing Thomas, who knows openacc better.
There is a devel/omp/gcc-12 branch you might want to try. I don't know
how different that branch is wrt openacc.
HTH,
