It times out eventually but this hangs on all our powerpc64 systems.  I let it
run on one with no timeout and it was still going after 90 minutes.

Mine. It is a testcase issue. A simple s/char/signed char/ should fix it.

    Fix pr115388.c: plain char could be unsigned by default [PR115415]

    This is a simple fix to the testcase as plain `char` could be
    unsigned by default on some targets (e.g. aarch64 and powerpc).

    Committed as obvious after quick test of the testcase on both aarch64 and
x86_64.

            * gcc.dg/torture/pr115388.c: Use `signed char` directly instead
            of plain `char`.
