8 years ago Thanks. Is this reproducible? Is the video available for testing?

VLC crashes after playing video for a couple of seconds. I have attached the back-trace below, let me know if you need anything else. I also attached the CPU info since it seems to be problem with some vector creation. backtrace

issue
VLC crashes after playing video for a couple of seconds. I have attached the back-trace below, let me know if you need anything else. I also attached the CPU info since it seems to be problem with some vector creation.
EDIT: My guess is that it run out of memory or something like that since all the videos pretty much crash at the same time after starting.
