You are right: 512 MB is enough to pass the example reformulated by 
Stéphane and Christophe, not to pass its original version with 
driver("PNG").

But when i increase the java heap to 1 GB, your original script passes 
without error:

--> exec('test.sce', -1)

   "SCREEN: Time to plot = 1.2227456s"

   "HEADLESS: Time to plot = 33.772641s"

By the way, beside the driver() discussion, the Java memory consumption 
of the grayplot family is known for a long time:
