    Add 'g++.target/nvptx/alias-g++.dg_init_dtor2-1.C'
    
    ... as one minimized example for the issue that with nvptx '-malias' enabled
    (as implemented in commit f8b15e177155960017ac0c5daef8780d1127f91c
    "[nvptx] Use .alias directive for mptx >= 6.3"), there are hundreds of
    instances of link-time 'unresolved symbol [alias]' across the C++ test 
suite,
    which are regressions compared to a test run with (default) '-mno-alias'.
    
            PR target/104957
            gcc/testsuite/
            * g++.target/nvptx/alias-g++.dg_init_dtor2-1.C: Add.
