--- Comment #2 from gong_su at hotmail dot com --- Hi Dominik, the command that failed with go1 internal error has a lot of .go files specified so I don't know which one actually caused the problem. So instead I can send you the entire Ethereum build tree so that you should be able to reproduce the problem by simply unpacking the tar.bz2 file somewhere and doing a "make geth". I can't attach the build tree here since it's 64MB and the limit for attachment is 1MB. Let me know if you want me to email you the build tree. Thanks.
