I'm having trouble getting it to work, but I was noticing that the clang-complete process was never running. Trying to run it resulted in crashes. I'm using a recent git build of clang.

It is a known issue that clang_complete would crash when being brought up with no command line arguments specified, it expects to accept one sourcefile name plus some other compiler options and it would work well when invoked by the (start-process) call in (launch-completion-proc), maybe it is time to check if the clang_complete executable has been placed to the right path, and if (launch-completion-proc) is properly called and completion-proc refered to a valid process.
