This isn't really an answer to your bug report, but it counts as a
workaround...

If you are developing this tool, please, please, please use DWARF-2
instead! The DWARF writer is on its last legs, especially in C++, and
the format is inferior.

He *must* be referring to DWARF2 already.
DW_DLV_NO_ENTRY is an error value returned by the libdwarf dwarf2 library
SGI wrote (and Intel rewrote, and Ulrich Drepper is writing for elfutils).

Oh, thanks. I'm not familiar with that library's API... it's on this
drive somewhere...
In that case, will the submitter please provide a testcase? Does
readelf show anything that looks wrong? It might be a bug in
libdwarf...

These are problems with DWARF-2 not the original DWARF.

Oops... I was unclear. It is DWARF-2 that I'm using.

I'm under too much of a time crunch to submit a very small test case. I
could only provide a large, unstable, difficult to install program which
probably wouldn't be much help.

I don't have time to generate a test case because I have a work around.
If it is waiting on me, just close it.

I figured that Daniel (being one of our debug specialists) would probably know about problems in
this area. But fair enough, we can close this, and if it comes up again (or Daniel confirms it is still a
problem), it can be reopened.
