Re: vdr[75260]: double free or corruption (out)
« Antwort #1 am: Juni 30, 2021, 06:50:08 Nachmittag »
VDR schließt Filter und benutzt die Instanzen im Nachhinein noch weiter und verursacht Memory Corruptions, der Bug liegt im VDR (sollte da noch weitere Hilfe benötigt werden lass es uns wissen).
Failure is a good thing! I'll fix it
