Remember to add virtual destructors to virtual classes!
Note that the compiler will suggest you that (if only AGG
code gave less warnings on its own...)

That comment refers to a performance issue and should not be related.

Does the movie eat immediately so much memory or does it become accumulated with each frame?

Can you try with a different renderer?

Found this comment in the TODO list, seems related to our problem:
 
 - Converted fill styles (for AGG) are recreated for each sub-shape, even if they never change for a shape. This should be
changed.

Udo, can you confirm this might be the problem ?

This flash ad also causes memory hogging:

I believe I was using agg - here's my output from running gnash --help on the commandline - however, I did (after the incident) rebuild gnash from CVS to get the latest version, so I can't verify for sure that it was agg prior to the rebuild, but I didn't change any build options, so I'm betting that it was agg.

Build options cvs-20061115
   Target: x86_64-pc-linux-gnu
   Renderer: agg   GUI: gtk   Sound handler: gst   Decoder: none

Tried with cairo backend and I don't get that huge eat-up, rather memory allocation seems rather stable (using top to see). It's around 13M.
What renderer were you using ? (can't use opengl from here)

Confirmed! It starts eating memory when the two batteries are one near the other, and float... The reduced url works as well:

This was from a Flash ad while browsing in Firefox - I'm not sure the exact URL that caused it, but here's the command-line that gnash was called with from the browser:

I'm running Shockwave Flash 8.0 - Gnash cvs-20061107 on an AMD64 system.

I'm not sure how to recreate this, as it was a random ad in rotation on some web site (not even sure which website - had multiple tabs that I had just opened when the problem occurred, and several of the new tabs had Flash ads on them, so I don't know the exact culprit).
