A bug report is a bug report.

And a patch is a patch.

These are different things. In a bug report you have to make the issue 
clear and enable others to reproduce the issue. No one expects you to 
come up with an explanation of what's wrong inside, what needs to be 
changed or even with a patch.

Here is an example of a really bad style report:

http://gcc.gnu.org/PR49764

But back on-topic: I think it's a good exercise for you to file these 
bug reports. Just think one minit what someone else needs to reproduce 
the artifact.

Some posts in avtfreaks contain C source that triggers the bug. Do 
binutils deal with C source code? NO! So get rid of the C-scrap by 
piping the source through the compiler by means of

$ foo-gcc -S file.c [your options]

et voilà: you have kicked of the C scrap away: one barrier less for the 
binutils guys.

- What version did you use? You know how to get it.
- What command line options did you use? Who will know it if not you?
- Waht's the error(message)? You know it.

As I already said: Just do that "no-excuses" reports.
You are skilled enough for that.

Without a report the prospects are really thin that a bug gets fixed.

But it's much more fun to chat in avrfreaks an post hacks around the 
bugs. And every some months some other guy is caught by the bug and the 
topic bubbles up in avrfreaks again and again (free software is scrap 
from hobbyists, we all know it).

All the poor developers would never come to avrfreaks if there were no 
bugs...
