Profiling bug in 6.10.4
by Gregory Wright 01 Apr '10

01 Apr '10

Hi, I have a program (attached) that is relatively simple, but numerically intensive. It computes the abundances of the chemical elements generated by big-bang nucleosynthesis. At the moment, the executable takes no command line arguments, it simply runs the standard model. When I build the program without profiling, it produces the right answer. When I build it with profiling (runhaskell configure --enable-executable-profiling) it runs without error, but gives completely incorrect numerical results. I'm using ghc 6.10.4 built from source using MacPorts. The program is mostly self contained, but uses the hmatrix package to solve a linear system. Note also that the "Vector" type is hmatrix's Data.Packed.Vector and not the one from the more familiar "vector" package. I was wondering whether this profiling problem is known. Best Wishes, Greg

Plans for GHC 6.12.2
by Ian Lynagh 01 Apr '10

Hi all, This is a summary of our plans for GHC 6.12.2. We plan to put out a release candidate 6.12.2-rc1 shortly and, assuming there are no serious regressions found, 6.12.2 will follow soon after. The bugs that we're planning to fix for 6.12.2 are the high priority tickets in the 6.12.2 milestone: http://hackage.haskell.org/trac/ghc/query?status=new&status=assigned&status… If there is a bug not in that list that is important to you, please let us know. Thanks Ian
