It's really all PTA memory.

Mainline:

 tree PTA              :   0.01 ( 0%) usr   0.00 ( 0%) sys   0.00 ( 0%) wall   
  40 kB ( 0%) ggc
 TOTAL                 :   2.18             1.05             3.44             
48857 kB

max. VM usage: 63MB

4.2:

 tree PTA              :  18.41 (88%) usr   1.08 (53%) sys  20.32 (85%) wall   
3903 kB ( 8%) ggc
 TOTAL                 :  20.92             2.02            23.94             
48672 kB

max. VM usage: 1.1GB

4.1.2 uses 56MB.
