vdr-plugin-neutrinoepg (unter yavdr) löst segfault aus

obelix · April 8, 2025 at 8:34 PM

Hallo zusammen,

beim Aufruf des NeurinoEPG Plugins startet der VDR mit einem Segfault neu:

Ich kann den Crash nachvollziehen, da wird wohl ein Nullpointer für tItem dereferenziert: https://github.com/vdr-projects/v…r/osdmenu.c#L61

Unabhängig davon wirft der Compiler auch jede Menge Warnungen: https://launchpadlibrarian.net/778995916/buil…BUILDING.txt.gz

Falls jemand Patches hat, baue ich die gerne ein, ich bin da noch nicht ganz durchgestiegen, was da beabsichtigt war.

Ich habe jetzt einfach mal einen Check für den Nullpointer eingebaut, damit ist der Crash beim Aufruf soweit ich das sehen kann weg: https://launchpad.net/~seahawk1986-h…g-archive-extra

obelix · April 9, 2025 at 8:58 PM

Jetzt funktioniert der Aufruf aber es werden keine Daten / EPGs angezeigt.

seahawk1986 · April 9, 2025 at 10:07 PM

Das kann ich auf meinem System leider nicht nachvollziehen - welchen Skin nutzt du?

Habe auch andere probiert, kein Erfolg. Ich finde auch keine Auffälligkeiten im Syslog.

Ich bin auf Version 2.7.3 zurück und da funktioniert neutrinoepg.
