Yes, it doesn't work at all, with and without a mapfile, and I guess
that format changes occurred in the lkcd dump because of this message
crash: LKCD machine specific dump header doesn't match crash version
crash: traceback of currently executing threads may not work
I'm debugging that now. But, if you have some patches already in the
queue that I can try out or something like this, I would be happy. ;)

I know the format of map files. :)
But the problem was easy to fix, see my attachment. You aggree that
the string length must only be smaller. The problem occurs on IA64
here.
