Sadly, there is not much I can do here :( I keep trying your method of reproduction, but I cannot get (or see) any meaningful reason why this is failing. The only thing I did see that was curious was: When running like this (using gdb to call efl functions and produce an error), the e_signal functions do get called, which in turn does call e_alert_main (thus the white box), BUT what I see happening is that gdb is intercepting the kill(e_pid, SIGUSR2). This causes major problems !!! as now E itself is stuck in pause thus when e_alert_main tries to send the 'restart' command, E never gets to processes it because it (E) is still stuck in pause because gdb intercepted the sigusr2. I am not sure what (if anything) can be done wrt this. The best advise I can give would be to use the 'set unwindonsignal on' as this allows E to receive the SIGUSR2 and thus continue with the restart. dh ------------------------------------------------------------------------------ Special Offer -- Download ArcSight Logger for FREE!
