Issue created Apr 06, 2014 by MichalGajda@trac-MichalGajda

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.

  • ** SpecConstr:

#################### SpecConstr

Result size of SpecConstr

STEPS TO REPRODUCE:

  1. cabal install hPDB

RESULT EXPECTED: Successful compilation and installation

CURRENT RESULT: Exhausts available memory and crashes when compiling Bio.PDB.EventParser.PDBEventParser.
