Note that the memory is still lost if you use /dev/null as the input stream.
This makes it easier to reproduce and suggests some things. Like that the
program is inappropriately building subtitle overlays for each subtitle when it
reads the subtitles rather than when they are needed and that it may be
misbehaving at end of file and continuing to produce subtitles.
There are 215 subtitles in the subtitle files. At 32 bits per pixel (RGBA),
these would account for 297MB.
Some other reports of massive memory leaks in spumux:
http://bbs.archlinux.org/viewtopic.php?id=51381
http://1010.co.uk/2007.01.20.html
One suggested that the problem wasn't present on older kernel versions or 32
bit systems. It is a couple years old.
It also reports causing the system to totally freeze after swap is exhausted.
One suggests using mencoder instead of spumux, but this isn't an option with
dvdstyler.
This is a critical bug due to the ability to crash the system.
