As far as the TUI is concerned:
It's broken with Solaris Native debugging.
I've spent a few hours debugging that problem but I have not solution yet !!
I also tried using deprecated_get_selected_frame without any better
results :(
This problem is present in the CVS HEAD but also in the 6.6 released
version, so I don't think it comes from recent changes.

P.S. here is the backtrace I got in the native solaris TUI
Program received signal SIGTTIN, Stopped (tty
input).
