--- Comment #6 from fortranbug at gmail dot com --- Thank you for the suggested workaround. This can certainly be helpful in the short term. However, we would not want to rely on tuning compiler optimization switches in the future to ensure correct code operation. (Our system is used by a community of users and it is not possible for us to ensure that they all use specific optimizations switches.) Can someone clarify the status of this bug report? Is this a recognized issue that will be addressed at some point?
