This is a false positive, please disregard this report.

This CI job cross-compiles the test binaries from x86_64 to aarch64 and arm and runs it under QEMU, but there's a problem with the cross-compilation. I checked the native aarch64 and arm jobs and in those cases all tests in team_allocated_coarrays.f90 pass. Everything is fine.

Sorry for the noise.

The problem is that the test binary tries to load libraries from the host path rather than from the CI toolchain's sysroot:

Running on qemu: timeout -k 30s 630s /home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/scripts/qemu-wrapper.sh x86_64 aarch64 any /home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/builds/destdir/x86_64-pc-linux-gnu/aarch64-linux-gnu/libc ./team_allocated_coarrays.exe spawn [open ...] aarch64-binfmt-P: Could not open '/lib/ld-linux-aarch64.so.1': No such file or directory aarch64-binfmt-P: Could not open '/lib/ld-linux-aarch64.so.1': No such file or directory ERROR: Image 1(pid: 3135800) failed with signal 0, exitstatus 255. aarch64-binfmt-P: Could not open '/lib/ld-linux-aarch64.so.1': No such file or directory aarch64-binfmt-P: Could not open '/lib/ld-linux-aarch64.so.1': No such file or directory aarch64-binfmt-P: Could not open '/lib/ld-linux-aarch64.so.1': No such file or directory aarch64-binfmt-P:aarch64-binfmt-P: Could not open '/lib/ld-linux-aarch64.so.1': No such file or directoryCould not open '/lib/ld-linux-aarch64.so.1': No such file or directory

This happens with several testcases, not only team_allocated_coarrays.f90.

I don't know if it the problem is in the testsuite or in our CI scripts.
