--- Comment #1 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
I found that PR108698 "decltype ((T() + ‘excess_precision_expr’ not supported
by dump_expr<expression error>)) median(ndarray<T>) [with T = double]’: since 
r13-3290-g98e341130f87984a" discussed a similar issue, but I don't know if it's
actually related.

    testsuite: Fix up depobj-3.c test on i686-linux [PR112724]

    While I've posted a patch to handle EXCESS_PRECISION_EXPR in C/C++
    pretty printing, still we'd need to handle
    (a + (float)5)
    and
    (float)(((long double)a) + (long double)5)
    and possibly
    (float)(((double)a) + (double)5)
    too for s390?, so the following patch just uses -fexcess-precision=fast,
    so that the expression is always the same.

            PR c++/112724
            * c-c++-common/gomp/depobj-3.c: Add -fexcess-precision=fast as
            dg-additional-options.

    c-family, c++: Handle EXCESS_PRECISION_EXPR in pretty printers [PR112724]

    I've noticed that the c-c++-common/gomp/depobj-3.c test FAILs on
i686-linux:
    PASS: c-c++-common/gomp/depobj-3.c  -std=c++17  at line 17 (test for
warnings, line 15)
    FAIL: c-c++-common/gomp/depobj-3.c  -std=c++17  at line 39 (test for
warnings, line 37)
    PASS: c-c++-common/gomp/depobj-3.c  -std=c++17  at line 43 (test for
errors, line 41)
    PASS: c-c++-common/gomp/depobj-3.c  -std=c++17  (test for warnings, line
45)
    FAIL: c-c++-common/gomp/depobj-3.c  -std=c++17 (test for excess errors)
    Excess errors:
    /home/jakub/src/gcc/gcc/testsuite/c-c++-common/gomp/depobj-3.c:37:38:
warning: the 'destroy' expression ''excess_precision_expr' not supported by
dump_expr<expression error>' should
    +be the same as the 'depobj' argument 'obj' [-Wopenmp]
    The following patch replaces that 'excess_precision_expr' not supported by
dump_expr<expression error>
    with (float)(((long double)a) + (long double)5)
    Still ugly and doesn't actually fix the FAIL (will deal with that
    incrementally), but at least valid C/C++ and shows the excess precision
    handling in action.
