Hmmm. Not sure. Shouldn't something have caught that exception? IOW,
could that be a bug?

I'm having difficulty figuring it out, because when I run the test
I don't see that output anywhere in the gdb.log:

(gdb) printf "x %d x\n", $tracepoint
x 2 x
(gdb) PASS: gdb.trace/report.exp: tfile: 9.1: find frame for TP 2
tdump
Data collected at tracepoint 2, trace frame 0:
(gdb) PASS: gdb.trace/report.exp: tfile: 9.1: tdump, nothing collected

I wonder what's different in our environments.
