Thinking a little bit more, the conditional breakpoint is also
kind of a red herring here. What really matters is the infcall.

So the testcase could just do:

(gdb) p (int) cmp3(word)

I'd simplify the testcase a little bit in that direction,
and call it gdb.cp/nodebug-infcall.exp, for example.

Note, the testcase should be gated with a

if [target_info exists gdb,cannot_call_functions] {

check.
