According to some docs I found the heap on the Visor Platinum running
PalmOS 3.5 is 256k.

I found that the crashes I got were with an old version of the plucker
database which included images of up to 640x480x4, which is decidedly
larger than 64k :)
With a new version with 320x240x4 images all seems to work fine.
