Re: [PR 55238] More careful pass-through handling in find_aggregate_values_for_callers_subset

[David Edelsohn]

        * testsuite/gcc.dg/torture/pr55238.c: New test.

Does this PR rely on hidden visibility?  The new testcase uses
attribute visibility hidden, but does not check DejaGNU
dg-require-visibility and fails on AIX.

void __attribute__ ((visibility ("hidden"))) gz_error (gz_state
*state, int err, char *msg)

Thanks, David
