        * omp-low.c (finish_taskreg_remap): New function.
        (finish_taskreg_scan): If unit size of ctx->record_type
        is non-constant, unshare the size expression and replace
        decls in it with possible outer var refs.

        * testsuite/libgomp.c/pr80809-2.c: New test.
        * testsuite/libgomp.c/pr80809-3.c: New test.
