(In reply to comment #9)
> I don't understand - why should dsymutil be needed at all? It isn't needed for gcc.

Au contraire - put the following in test.c:
----
int main()
{
    return 0;
}
----
then:
$ gcc -v -g test.c -o test
or
$ clang -v -g test.c -o test
You'll notice the last command run by either is dsymutil test.

I may have found what dsymutil is choking on, I can't be sure though - following the steps taken by gcc, then removing the object file it creates before running dsymutil causes dsymutil to complain that <object file> does not exist. Curious, I inspected the binary with a hex editor, and it appears ld left some information in there that dsymutil requires, a list of object files. It seems ld doesn't do this for dmd, so I suspect there's something else we're not outputting that's required, or some flag we need to pass to ld. I blame ld, as there is no mention of the object file(s) in themselves before linking. I'll hunt a bit further, I'm not sure how much I can do without more knowledge of what's going on.

So DMD should invoke dsymutil?

I believe so, there's not a lot of point right now though, given that the binaries produced by dmd cause dsymutil to fail. Struggling to find out what needs changing to stop dsymutil failing.

You don't need to run dsymutil.
The final executables do usually not contain debug infos, but they do
contain the path of all object files that were linked. Debuggers will use these
to get the debug infos from the object files.
Also GDB will load debug infos from the executable.

Is this still an issue or not?

Nope, the underscore fix is already in the compiler.
