Also saw the same issue  on x86 target.

On Linux/x86_64,

    testsuite/101114: Adjust libgomp.c-c++-common/struct-elem-5.c testcase

    The dg-shouldfail testcase libgomp.c-c++-common/struct-elem-5.c does not
    properly fail for non-shared address space offloading. Adjust testcase
    to limit testing only for "target offload_device_nonshared_as".

    libgomp/ChangeLog:

            PR testsuite/101114
            * testsuite/libgomp.c-c++-common/struct-elem-5.c:
            Add "target offload_device_nonshared_as" condition for enabling
test.
