Comment(by nudded):
I used several debug flags. The output of dump-occur-anal seems to
increase in size when adjusting the size of the LargeState transformer
stack. So, in the attached code LargeState consists of 10 StateT
transformers.
When compiling with 7 it will still work. When compiling with 8 it will
try to allocate > 4 gigs of memory.
Those are some of the observations I ran into when trying to figure out
what is going on.
Sidenote: when compiling without optimisation there is no problem at all.
