malloc error when using -f ffmetadata

[dave rice]

I'm getting an error when trying to output the ffmetadata format. I tested an mov, mp4, and mpeg file with the same resulting error.

Here's an output using ​http://samples.multimedia.cx/mov/P6040064a.MP4

ffmpeg -i P6040064a.MP4 -f ffmetadata -

Tested in Linux and works fine, seems and OSX related problem, maybe related to #255.

A work-around was applied to current git head.
