Thanks.

So, threaded, non-optimised build.

Within Perl_switch_to_global_locale(), the memory is being allocated by

    for (unsigned i = 0; i < NOMINAL_LC_ALL_INDEX; i++) {
        curlocales[i] = querylocale_i(i);
    }

and freed  20 lines down in

    for (unsigned int i = 0; i < NOMINAL_LC_ALL_INDEX; i++) {
        Safefree(curlocales[i]);
    }

And presumably being added to the save stack somewhere in-between.

Karl?
