GHC 6.4.3 is stalled

Folks GHC 6.4.2's threaded runtime system does not work right on Solaris MacOSX Possibly FreeBSD We'd love to fix these bugs and release 6.4.3, but we are stalled because we don't have easy access to these platforms, nor do we have detailed expertise in their intimate details (which is where the bugs will be lurking). If you care about these platforms, would you like to lend a hand? We probably need more help than simply "here's access to the platform", but we'd give you very strong support if you were willing to look into it. Failing that, I think we'll have to stick with 6.4.2. (And the same bugs may well show up in GHC 6.6, which we hope to release before ICFP.) Simon
