Compilation of large source files requires a lot of RAM

We have automatically generated source files with up to ~20000 lines of code.

One type definition, two functions called "grammar" (cmGrammer, ghGrammar) and one or more functions called "algebra" (prettyprint, scoremax, count, ***) are generated. Each function has a where-clause with 100+ locally visible function defined.

Attached, you find two files (ADPTriCombinators.lhs, RnaI.lhs) with helper-functions and three of our source files. One is the smallest example we have and the other the largest. RF00549RED.hs is reduced to only the type, one algebra and one grammar.

Copy all files into a directory and then execute:

ghc --make RF00390.hs (should work)
ghc --make RF00549.hs (WARNING: EATS ALL MEMORY)
ghc --make RF00549RED.hs (WARNING: EATS ALL MEMORY)
