FreeBSD: vlc in free(): error: modified (chunk-) pointer

[Humperdinck]

Dear Forum,

FreeBSD 6.2 and vlc-0.8.5_7. It rocks, I tell you.

The new http interface triggers a bug that most likely is FreeBSD related but I'll post it here anyway in case anyone knows a quick fix for it.

When running "vlc -I http" and using a browser to add a file, clicking 'play' for that file gives the following error message with a core dump:

vlc in free(): error: modified (chunk-) pointer

If anyone has a solution, please let me and the forum know!

Thanks In Advance

The issue seems to be resolved in the devel version (VLC media player 0.9.0-svn Grishenko).

Looks like a heap corruption (could also be a bug in libmatroska btw). Unfortunately, our matroska maintainer left
