[Octave-bug-tracker] [bug #50183] tempname() returns an empty string on Solaris

[Michele]

Follow-up Comment #11, bug #50183 (project octave):

"You answered "n" to the prompt about adding the pending breakpoint, so no
breakpoint was set. Try answering "y", run again."

Well I didn't know what to say and so I just took the default, which was n. 
This is what I get now:

Make breakpoint pending on future shared library load? (y or [n]) y

Breakpoint 1 (file-ops.cc:720) pending.
