On the trunk things look different:

 tree find ref. vars   :  22.59 (13%) usr   1.08 (13%) sys  24.42 (14%) wall 
815888 kB (47%) ggc
 tree PTA              :   1.43 ( 1%) usr   0.08 ( 1%) sys   1.39 ( 1%) wall  
19446 kB ( 1%) ggc
 tree alias analysis   :   5.64 ( 3%) usr   0.15 ( 2%) sys   5.71 ( 3%) wall   
1611 kB ( 0%) ggc
 tree call clobbering  :  15.15 ( 9%) usr   0.07 ( 1%) sys  15.56 ( 9%) wall   
 613 kB ( 0%) ggc
 tree flow sensitive alias:   1.85 ( 1%) usr   0.09 ( 1%) sys   2.06 ( 1%) wall
  96898 kB ( 6%) ggc
 tree flow insensitive alias:   1.79 ( 1%) usr   0.00 ( 0%) sys   1.68 ( 1%)
wall       0 kB ( 0%) ggc
 tree memory partitioning:  38.40 (23%) usr   0.53 ( 7%) sys  38.68 (22%) wall 
   820 kB ( 0%) ggc
 tree operand scan     :  11.31 ( 7%) usr   0.16 ( 2%) sys  11.76 ( 7%) wall  
58545 kB ( 3%) ggc
 TOTAL                 : 169.77             8.02           177.99           
1747899 kB

but the memory situation isn't different.
