P.S.  the fix seems to be this, though, naturally, I hate it.

static void
inner_main(void * closure, int argc, char ** argv)
{
    atexit(done_check);
    initialize(argc, argv);

    {
        char const * p = getenv("LD_LIBRARY_PATH");
        if (p != NULL)
            putenv("LD_LIBRARY_PATH=");
    }
