Module that causes GHC-7.8 to exhaust memory when -O2 is on
The repository at http://src.seereason.com/o2bug contains a package that causes GHC-7.8.1 (rc2?) to exhaust 16GB of RAM and die when the -O2 flag is turned on. I haven't been able to simplify it very much, almost any change to JSON.Render causes it to start working properly. I did get it to fail using only packages available in hackage. Just thought I should let folks know about this issue. Let me know if it fails to fail. Maybe someone who can log in could put this in trac.
