using autosave, iocInit hangs

[junkes via Tech-talk <tech-talk at aps.anl.gov>]

I was using EPICS 7 with RTEMS 5 and have now also enabled autosave.
Unfortunately in Main iocInit does not come back but hangs at the last
InitHookAnnounce in iocRun
...
    if (iocState == iocBuilt)
        initHookAnnounce(initHookAtEnd);

    errlogPrintf("iocRun: %s\n", iocState == iocBuilt ?
        "All initialization complete" :
        "IOC restarted");
    iocState = iocRunning;
    initHookAnnounce(initHookAfterIocRunning);
    return 0;
}






and no new iocsh(NULL) is started.

int main(int argc,char *argv[])
{
    if(argc>=2) {
        iocsh(argv[1]);   <----- here it gets stuck
        epicsThreadSleep(.2);
    }
    iocsh(NULL);
