[Octave-bug-tracker] [bug #55029] pause causes hang

[Mike Miller]

Follow-up Comment #34, bug #55029 (project octave):

I also observe the following on Fedora 29. When Octave starts, the 'kbhit'
function behaves correctly. However, after calling 'pause' with no arguments,
and breaking out of it with Ctrl+C, the 'kbhit' function now returns an empty
string immediately for the remainder of the Octave session. This agrees with
the change that Dmitri bisected to, which uses 'octave::kbhit' inside of an
infinite loop. The 'octave::kbhit' function continues to return -1 inside that
loop, no matter how many keys are pressed, so the loop is never broken until
the user issues an interrupt.
