--- Comment #1 from Hannes Domani <ssbssa at sourceware dot org> ---
Would it be possible to show exactly what is failing?

I got the debug.cc and compiled it, but for me "print redirected" never works
as I would expect it to, with gdb versions older than 14 as well.

So an example of how "print redirected" looks like when it succeeds would be
great.
