I somehow have the feeling that it could be a kernel bug, as I have other strange things happening as well which also could be caused by a kernel bug. As I am planing to upgrade to El Capitan today or tomorrow, I will wait with further test until then and let you know. Another pointer towards the kernel: the error only occurred after a holiday, which resulted in the upgrade of the OS, emacs, packages, ... So I could not pinpoint what caused it. > > I don't really understand what this means. I can only suggest to run > another session with the same commands, and see if it fails in the > same way. This was already the third session, as it also did not make sense to me. Also: continued "continue" resulted in exactly the same error message and no continuation. OK - I will then upgrade and report back in a few days time to see if the upgrade solved the problem. If it was kernel, I am really sorry for your wasted time, I will report back then, Thanks a lot, Rainer > > Thanks. =2D-=20 Rainer M.
