Actually all of the time is spent in the parser so this is not a middle-end problem.
Also note you did you did not disable checking which is enabled by default on non release branches.
parser : 20.34 (90%) usr 0.15 (19%) sys 22.35 (88%) wall
The compile time problems comes from transfering linked lists.
One is in resolve.c:3067-3076
Another is in symbol.c:1401-1403.
I don't know if the linked lists are long are just looked over and over. I am going to assume the former.
