I get the same thing using -gdwarf-2:

$ g++ -gdwarf-2 -o hello /home/wdowling/src/hello.cpp
$ ups ./hello
DWARF error :  dwarf_attr - no entry (DIE /home/wdowling/src/hello.cpp
<2643><11>)
Already saved typename rebind<char> in this CU <2632>

The message panel in ups shows
  Source file `/home/wdowling/src/hello.cpp/no entr9' nonexistent

Note the odd file name "no entr9"

With -gstabs+ and -gstabs I don't get any error message, but still the
source is not visible.  It's almost as though dwarf is being used OK,
but dwarf is not handling the path to the source correctly.

Thanks,

Will
