[eside-ghost] violacion de segmento

Lun Mayo 1 23:28:13 CEST 2006

Aupi,

Desde hace un par de días muchas aplicaciones cascan por una 'violación
de segmento', cuando hasta hace esos 2 días funcionaban perfectamente.
Que yo recuerde no he cambiado nada...

$ mplayer con_animo_de_lucro_divx.avi
Violación de segmento

(mplayer compilado e instalado desde fuentes)

$ vlc con_animo_de_lucro_divx.avi
VLC media player 0.8.4-svn20040920 Janus
Violación de segmento

....

¿A alguien se le ocurre algo? Por donde puedo empezar a mirar?

He probado a pasar un memtest y parece que la memoria no es el
problema...

La salida del strace es:

$ strace mplayer con_animo_de_lucro_divx.avi
