That 256-byter demo is also broken in vanilla SVN. It was released in January of this year, and like some other recent DOS demos that I've noticed on Pouet, it was apparently developed and tested using only DOSBox 0.74. It's understandable to use DOSBox for the convenience factor, but it's potentially problematic for compatibility (with real DOS and with later versions of DOSBox), as we've seen with that GP-01 demo a few posts back.
The demo causes an FPU stack overflow, and SVN has added an error exit for that condition. I'm not sure if Daum has included the error exit, but you can check the status window to see what is reported there. However, even without the error exit, the demo is still broken in SVN.
The demo expects that text printed by the console device in graphics mode will use attribute 15, as DOSBox 0.74 does; but it has been fixed in SVN to use attribute 7, as real DOS does. As such, the demo shows a blank screen in SVN (also in 0.74 when booting real DOS). FYI, the change to the console device in SVN has fixed demos that rely on the attribute 7 behavior of DOS, such as http://www.pouet.net/prod.php?which=63299
