Generally speaking, I tend to agree, but at the same time, it really
depends.

Is this specific to GDB 12, or did we have this issue with previous
releases?

We also need some kind of visibility as to how quickly we think we can
solve that issue. This usually requires someone to act as the issue's
"champion" -- that person might not be the one actually making the fix,
but they can at least try help expedite the process.

I'd start by asking Mike Frysinger, who's the sim maintainer.
He might not know about this particular target, but he's made
a lot of cleanups in this area.

In this case, hopefully the fix won't be too difficult.
