When compiling our sources I had two sources that failed with:
Context reduction stack overflow; size = 21
Use -fcontext-stack=N to increase stack size to N
Increasing to 30 helped. Another source
MultiParamTypeClasses, FunctionalDependencies, DeriveDataTypeable,
FlexibleInstances, UndecidableInstances, ExistentialQuantification
I wasn't able to compile yet. After 4 minutes it failed with:
Context reduction stack overflow; size = 46
and I'm increasing the context-stack further.
Maybe this is related to:
(ghc-6.10.x or ghc-6.12.x have no such problems.)
