I am encountering a hard fault in EwReclaimMemory() while executing EwMarkObject( item->Object );
I am able to reproduce this issue. May be it sems to happen after I update variables from native code including also a string variable. It happes if I access the the cooking prorgam is a dedicated order: manually load LAST cooking program start and stop cooking cycle; power off device (last settings are stored); power on device (last settings are loaded); manually load first cooking program -> next Call to EwReclaimMemory() cause hard fault.
Is there a way to debug the garbage collection to get some information what actions can cause this issue?
this is the code which is may be cause the problem:
