--- Comment #2 from zwieflhofer <walter.zwieflhofer at ineosteamuk dot com> --- Installed gcc-5.5.0 and built the identical WRF version. No ICE encountered with 5.5.0. Attempted to extract a reduced test version but this is non-trivial due to the large source code base and complex make files. I am happy for now that 5.5.0 gives me a working solution. I tried the reproducer attached to bug report 41062 but that one compiled fine under 7.4.0. Please regard this bug report as a courtesy rather than a request for action and feel free to close it due to the missing reproducer. Alternatively, I can forward this report to NCAR to see whether there is any interest in pre-emptive investigations as part of their regression testing. Many thanks for the prompt reply.
