http://d.puremagic.com/issues/show_bug.cgi?id=3987 Please ignore the attached patch file, it's the incorrect fix (although it does work). I haven't written a formal patch, I didn't see a need with it only being 2 lines needing removing (which are mentioned in my last post, and a comment on that bug).

As an update to the case it doesn't fix, it seems the second DW_TAG_formal_param is causing the debug info for something else to be written half way between the debug info for something else, so when it's read it's read incorrectly. Still working on this, I'm hoping to have a patch for it tonight, I've already put days into this, I'd rather not spend too much more ;)

I and I'm sure many others appreciate your efforts.

I've filed a bug report:
http://d.puremagic.com/issues/show_bug.cgi?id=4035
Sorry, cannot make the test case smaller.

And there is another that may describe the same bug:
http://d.puremagic.com/issues/show_bug.cgi?id=4009

Thanks :) I've finished a complete and working patch now, it's attached to http://d.puremagic.com/issues/show_bug.cgi?id=3987 and should fix the remaining issues with debugging info on linux. I've tested it with QtD, and various other projects, so I'd be grateful if you could review the patch and apply it!

Hopefully this is fixed with the patch from #3987, I've tried your test case and it works fine now.

Will do. Thanks very much!

There are a couple of other debugging patches that I created later on, they're attached to separate bugs:

http://d.puremagic.com/issues/show_bug.cgi?id=4037
http://d.puremagic.com/issues/show_bug.cgi?id=4038

It'd be good if you could apply them too :)

Thought I'd call your attention to:

http://d.puremagic.com/issues/show_bug.cgi?id=4044

I created a tracker bug for all the gdb/debugging/DWARF/etc issues with dmd, quite a lot of them already have patches, so while you're looking through my patches, making sure they're ok, could you take a glance at some of the others and pass comment? Thanks again :)
