SpecConstr usage explodes beyond 4GB with GHC 7.8.1 rc 2
GHC 7.8 rc2 exhausts all memory on Bio.PDB.EventParser.PDBEventParser
module in -O3 mode, but not in -O2 mode.
The tail of -v3 input seems to indicate that it dies during SpecConstr phase. The module successfully compiled with below 2GB RAM since GHC 6.12, so I wonder why the memory use exploded with the most recent version.
