It's good you told me, I will try to talk to some of my collegues
who work on the compiler and see where we are.

I use exclusively GNAT Pro, which is the compiler we maintain at
AdaCore. Right now, it's based on GCC 3.4.6, but are actively moving
to a GCC 4.1 backend on most of our platforms. That's when we found
a lot of issues in debug info generation that apparently appear only
with Ada - we have fixed several of them and I believe that they have
been submitted although I will admit that I do not follow compiler
work very closely.

If I started doing my testing with various flavours of GCC, the number
of combinations would explode. I already run our in-house testsuite (not
based on dejagnu) together with the GDB testsuite, both with our
GDB tree and the FSF head.

All I can say is that we're getting better at pushing our changes
to the FSF tree both on the GCC side as well as the GDB side, but
it's a slow process because first we have to catch up and then we
have to learn how to best do it.

In the meantime, are these fails an issue? For me, I have the same sort
of issue in a smaller scale with C++ testcases, but the way I test is
by using a smart-diff between the testcase results before and after.
