Dear GHC developers, I have tested ghc-7.8.2-src by making it by ghc-7.6.3 under Debian Linux. Then I have `made' my DoCon-2.12 application by ghc-7.8.2. It looks all right. For any occasion, here are some test results. Comparing it to ghc-7.4.1 shows the following. 1) The default context reduction stack (21) is not sufficient, so, I add -fcontext-stack=30 to the options. 2) The resulting libHSdocon-2.12.a is 1/10 larger (but the DoCon source is not the same, and it is, may be 1/100 larger). 3) The Main executable test size is almost the same. 4) The test running speed is the same. 5) The minimal -M memory setting for running the test is 4300 Kb against 2400 Kb of ghc-6.4.1.
