Hi,

the following code in myldr/utils.c line 239 looks suspicious. Shouldn't 
PAR_TMPDIR also be unset?

    par_unsetenv("PERLIO");

    par_unsetenv("PAR_INITIALIZED");
    par_unsetenv("PAR_SPAWNED");
    par_unsetenv("PAR_TEMP");
    par_unsetenv("PAR_CLEAN");
    par_unsetenv("PAR_DEBUG");
    par_unsetenv("PAR_CACHE");
    par_unsetenv("PAR_PROGNAME");

    if ( (buf = par_getenv("PAR_GLOBAL_DEBUG")) != NULL ) {
        par_setenv("PAR_DEBUG", buf);
    }

    if ( (buf = par_getenv("PAR_GLOBAL_TMPDIR")) != NULL ) {
        par_setenv("PAR_TMPDIR", buf);
    }

    if ( (buf = par_getenv("PAR_GLOBAL_TEMP")) != NULL ) {
        par_setenv("PAR_TEMP", buf);
    }
    else if ( (buf = par_getenv("PAR_GLOBAL_CLEAN")) != NULL ) {
        par_setenv("PAR_CLEAN", buf);
    }

Mit freundlichen Grüßen                         

Ralf
