The latest PTree implementation uses bit-stealing (fat pointers) and
defaults to three bits:

https://github.com/klee/klee/blob/master/lib/Core/PTree.h#L25

On 32bit systems you simply can't reserve 3 bits due to smaller
alignments. One could fix it but KLEE does not support 32bit host
systems anymore I'm afraid.


Kind regards,

Frank
