The problem occurs if lldb wants to support debugging ELFs produced on different hosts - i.e. if the producer and consumers of the DWARF are either POSIX/Windows. We could then have a situation where a comp_dir string is something like:

Actually I think you will be ok because it will be:

c:\home\source  for windows...

Feel free to modify the DWARF parser to strip off the leading hostname to get things fixed and working. If it is part of the older _or_ current spec, we should support it in LLDB.
