#2346: Compilation of large source files requires a lot of RAM
------------------------+---------------------------------------------------
Reporter: choener | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.8.2 | Severity: major
Keywords: | Testcase:
Architecture: x86 | Os: Linux
------------------------+---------------------------------------------------
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)
