what exactly do you mean by gdb froze? If you type continue psi will
not take any input, until your programm is halted again, either by
pressing ctrl-c in the gdb window or by some crash/breakpoint.

So if you have psi running in the frozen state, you would start psi
and attach it. psi will stop psi and load the symbols, as soon as it
again shows the gdb prompt you can type "bt" to get a stacktrace of
psi. 

the other way is to start psi from gdb: (approx like this)
$ gdb psi
(gdb) start
[now get psi to the hang]
<ctrl>-C
(gdb) bt
[stack trace follows]
