[Octave-bug-tracker] [bug #58378] bin2dec hangs

[anonymous]

Follow-up Comment #4, bug #58378 (project octave):

Leonardo,

I wouldn't mind receiving that tutorial.  It certainly wouldn't hurt
(steven.evans(at)BoolEngine.com).

I'm not sure that the problem is with the live DVD.  I installed Lubuntu 20.04
onto my computer, weeks ago, using that DVD.  I installed Octave, via the GUI
repository, right after installation.  It was working fine, from the
installation on that day, up until yesterday.  Then, yesterday, I was running
the program which uses bin2dec.  It's a time-consuming program.  It takes
several hours to run.  In fact, it's still running at this very moment, with
no problem.

After the program had been running for about a day, I opened a new console
window, and started another program, which uses the same subfunction that the
current, running, program is using.  when I started the new program, all it
did was hang.  If I start the exact same program, which is currently running,
in a different window, on the same computer, it hangs.

So I ran the Lubuntu 20.04 live DVD on a different computer, and noticed that
it hangs on that computer too.  I narrowed down the line were the program was
hanging.  It's a single line which uses the bin2dec function.  I saved the
input content, which was going to bin2dec, and have been able to reproduce the
error, over and over again -- Not just with the input that I saved, but also
with a random character matrix of the exact same size.

The computer, which is still running the working function, isn't hooked up to
the internet.  So I'm still not completely sure why any new sessions don't
work.  The system hasn't even been powered down.  All I know is that bin2dec
hangs now, with new sessions when given matricies of that size.  I should also
note that a smaller matrix, one with only two or three rows, works without a
problem.  So it's all very bizarre.

When you installed Lubuntu 20.04, did you first burn it to a CD/DVD?  If so,
do you still have that CD? I'd be curious to see if that DVD, when run live,
produces the same problem.  The installation, on my hard drive, worked for
weeks with no problem.  So it doesn't shock me that it works on your installed
Lubuntu 20.04.  Who knows, maybe tomorrow, it will start to have the same
problem as mine.  It's very strange.
