#2658: Extreme memory usage
-------------------------------+--------------------------------------------
Reporter: guest | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler (Type checker)
Version: 6.9 | Severity: major
Keywords: | Testcase:
Architecture: x86_64 (amd64) | Os: Linux
-------------------------------+--------------------------------------------
This is with the ghc 6.10.1 rc:
http://darcs.haskell.org/ghc-STABLE-2008-09-19-ghc-corelibs-
testsuite.tar.bz2, unpacked, then ./darcs-all --extra get and ./darcs-all
pull -a
Then a perf build.
Then, wget
http://hackage.haskell.org/packages/archive/sessions/2008.7.18/sessions-2008.7.18.tar.gz,
unpack and cd sessions-2008.7.18
ghci-6.8.3 Tests/Tests.hs. This takes 40 seconds to get to the prompt and
uses about 700MB memory.
ghci-6.10.0.20081004 Tests/Tests.hs. This has not finished type checking
yet (well over 5 mins now - it exhaused my 4GB RAM and is now eating its
way through 16GB of swap). top reports it's currently using about 5GB
memory.
