Now they seem to both be correct. The key value is at the bottom of column 8. This should be 2.386e-1 (which means that 23.86 percent of the protons in the early universe end up as helium). So it seems that this is a problem either with 6.10.4, or with OS X.
Quite strange. I will try to get 6.12 building on my machine to see if the problem persists.
It would also be worth trying without the -optc-O3 and -optc-ffast-math flags, as the different code generated may confuse the mangler.
If none of that helps, can you file a ticket please? If you can boil it down to a small self-contained testcase (in particular, removing the hmatrix dependency, if necessary by inlining code you need from it) that would make it easier to investigate.
Thanks Ian
Removing -optc-O3 and -optc-ffast-math did not help. In fact, I took at all of the ghc options I was passing and the problem is still there. I will try to reduce the failure to a self contained testcase. I don't use much from hmatrix --- aside from the LU solution for a matrix system, just basic matrix addition, subtraction, scaling and the dot product. Best, Greg
