--- Comment #8 from Paul Thomas <pault at gcc dot gnu.org> --- Linaro flagged up this failure, when I submitted the patch for approval. Following some correspondence with Thiago Bauermann, this conclusion was arrived at: "I ran your patch through a different CI loop that we have, where instead of using the distro's toolchain (binutils, gcc, glibc) to build and test the patch, it builds every component from scratch and from their respective tips of trunk. This time it didn't detect any problem. All gfortran.dg/class_transformational_2.f90 tests passed: https://ci.linaro.org/job/tcwg_gnu_native_check_gcc--master-arm-precommit/2/artifact/artifacts/artifacts.precommit/sumfiles/gfortran.sum.xz I think this means that with Ubuntu 22.04 glibc we see the problem, but when using the latest upstream glibc we don't." What should I do? I don't see the failure at all. Unlike class_transformational_.f90, valgrind gives this test a clean bill of health. Regards Paul
