I used 7.0-CURRENT (GENERIC without debugging stuff) and ports both from October 1st 2007. jdk-6u1 built and installed without problems for me. I also tried jdk-6u2 without "success"; it worked fine. So I strongly disapprove the change of GCC to not use tree-vrp by default and I want to suggest that you change it back. GCC 4.2 seem to have many bugs and I think it's the wrong way to change it's default behaviour to work around these bugs, because this reveals other bugs. If you are still able to reproduce the error (e.g. with explicit -ftree-vrp) then I would be glad if you can provide detailed information about the environment. I want to get the same error, because I'm searching for a more suitable solution, e.g. a better GCC patch. Regards Björn
