Note that the code compiles but not all tests pass, so some additional work will be needed before this gfortran version can be used.

Dear Jos Can you tell us precisely which tests fail?

Dear Jos Can you tell us precisely which tests fail?

Sure. I see the following 4 tests fail after applying these patches and running the tests:

The following tests FAILED: 179 - eccodes_f_grib_copy_message (Failed) 180 - eccodes_f_bufr_copy_message (Failed) 198 - eccodes_f_read_message (Failed) 199 - eccodes_f_read_from_file (Failed) Errors while running CTest

For your reference I also attached the logging output of the 4 test cases when I run them with extra verbosity like this: ctest -VV -debug -R "eccodes_f_grib_copy_message|eccodes_f_bufr_copy_message|eccodes_f_read_message|eccodes_f_read_from_file" > log.txt 2>1 eccodes_2.15.0_failing_tests_gfortran_v10.txt.gz Two of them show an ugly segmentation fault, and 2 others seem not ably to detect the 7777 code at the end of the grib message.
