Segfault auswerten

lancs · 18. August 2013

Hallo Leute,

kann den Segfault jemand auswerten?

Das ganze tritt auf wenn ein Timer anliegt, und der VDR beim abspielen von VDR-Aufnahmen oder Videos via MPlayer ist.

Hallo Leute,

kann den Segfault jemand auswerten? ...

Wenn Du den VDR mit Debug und ohne Optimierungen baust, dann evlt. schon.

Sieht aus wie ein Zugriff über die Grenzen eines Arrays hinaus. Schau doch mal in audio.c Zeile 2779 nach.

Wobei das

auch recht unitialisiert ausschaut

OK, ein cflags/cxxflags -O0 in der vdr.pc und ein

make DEBUG=1

sollte ich gerade noch hinkriegen
