Application Configuration - Preemptable ISR option

Some time ago I had an issue when activating the "Preemptable ISR" option in application configuration for SPC56EL. I posted it in the SPC56 forum. Now my software for SPC560P shows also a strange behavior when I activate that option.
I created a very simple software. Just the while loop in main.c which increments a variable and one interrupt triggered by an external PWM signal. When the "Preemtable ISR" option is deactivated everything works as expected. But if I activate the option, the software stops after a random time (around 10 seconds). The debugger shows me, that the software halts at the address 0x000000E0. I think that there is again a problem with this "Preemtable ISR" option in application configuration.

Best regards,
