I've switched to redhat9 and now I get thread info, but I'm having other
problems instead. Strange behaviour which I believe shouldn't happen.
When I step forward in the code it seems to be running into somekind of loop
running the same lines of code several times when it shouldn't, as you can see
in the gdb session below. This is with gdb 5.3.91 but I saw the same behaviour
with 5.3 on my gentoo box at home.

Any thoughts ?
