stripped down testcase
Stripped down, now it starts to fall off a bit:
tree SSA incremental : 1.48 ( 7%) usr 0.42 (33%) sys 1.96 ( 8%) wall
1882 kB ( 1%) ggc
dominator optimization : 10.57 (50%) usr 0.03 ( 2%) sys 12.44 (48%) wall
6918 kB ( 4%) ggc
TOTAL : 21.12 1.27 25.67
191269 kB
(just cutting in half three times from the bottom and appending } until it
compiles again)
