#9971: GHC 7.10 dies with "out of memory" -------------------------------------+------------------------------------- Reporter: albertov | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1-rc1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by albertov): I've created a [https://github.com/meteogrid/sigym4-geometry/tree/ghc-9971 new branch] in my library to track this down from the first revision that causes the problem (2b00e8f5052cc392). I've removed the `-O2` flag from the `test` section of the .cabal file (the library section didn't have it) and configured with: `cabal configure --disable-optimization --ghc- options="-v3" --enable-tests -w /usr/local/bin/ghc-7.10.0.20141222`. The output of the configure step is: {{{ Resolving dependencies... Configuring sigym4-geometry-0.1.0.2...
