compiling cabal-1.24.2.0 requires almost 3 GB of memory
Not sure if this is really a bug, but I noticed that ghc-8.2.2 requires a whole lot more memory than ghc-7-10.3. This is how I found out about it:
ben@yuiitsu[1]:.../src/Cabal-1.24.2.0>ulimit -v 2600000
ben@yuiitsu[1]:.../src/Cabal-1.24.2.0>cabal new-build

Build profile: -w ghc-8.2.2 -O1
In order, the following will be built (use -v for more details):
- Cabal-1.24.2.0 (lib) (first run)
Configuring library for Cabal-1.24.2.0..
Preprocessing library for Cabal-1.24.2.0..

ghc: out of memory
cabal: Failed to build Cabal-1.24.2.0 (which is required by
darcs-2.13.0). The
build process terminated with exit code 251It works when I ulimit -v 3000000.
I previously had the limit at 2200000 and it worked just fine with ghc-7.10.3. The reason i limit the memory available to ghc is to avoid my machine freezing up due to thrashing (I only have 4GB physical RAM).
