#2 hint combined with create causing huge memory use

[Daniel Bonniot]

I ran into a situation where using both -create and -hint in the same run uses huge amount of memory (75% of physical ram, that is 1.5GB) on a ~20MB input. That is when adding a h264 track, after an acc is already there (with hints). When I run -create first and -hint later, all seems fine. Is this a known bug?

If you need to file to reproduce, given the relatively big size, let's discuss that in private.
