-------------------------------+--------------------------------------------
GHC 7.6.1 on x86_64-lines from Debian's experimental repo (Debian unstable
is currently frozen in preparation for the new release and therefore the
Debian Haskell team is uploading to experimental).
I have 50 lines of code across two files and then I compile these with -O1
the compile competes in about 10 seconds. However if I compile it with -O2
or greater, the compile does not seem to terminate. I've left it for as
long as 1o minutes and the compile process uses 100% CPU and its memory
usage seems to grow slowly so that after 10 minutes its using 5% of my
machine's 8Gig or memory.
