Hi All,

Just a FYI, I did an update on a Linux install and wound up with a segmentation fault. Untarring the exec archive did not do the trick.

This is all the data I could come up with, hope it helps. I think it has to be something changed within the last 48 hours.

Looks like Deuce committed a fix to CVS already. Sorry about that,

Not a problem, I had the original copy saved in another location, copied it over and recompiled it.

Re: Binkit & Segmentation Fault
By: Ray Quinn to All on Sun Feb 17 2019 09:14 am

I am going to address the segmentation fault first.

After downloading the latest development source on Tursday February 14, 2019 and compiling it, SBBS would not run. I am running Debian Stretch. I tried the GDB method to see about getting a core file, no good.

gdb /sbbs/exec/sbbs /tmp/core.sbbs.0001

What does that mean - no good?

It didn't create any core, it ran as long as it did trying any other method I mentioned.

I ran it several times in a console window and got a segmentation fault at various stages.

Try a clean rebuild.

I do a clean build every time.

I went to my source backup, compiled it, and all is well. I
likely have no other information to provide. I will try again later today and, if it fails again, get more information.

Run src/cleanall.sh before your next build.

I ran this script, too. A clean build usually generates fewer issues. I will try again when I have
more time to mess with it. The older source is working for now. I just like to try to keep up with
any new changes, etc. Thanks!

You don't have core files from the previous segfaults? You don't need to run sbbs from gdb to get a core dump file created upon segfault. Check your /tmp directory or wherever you have your system configured to save core dumps.

you might have to set your ulimit, too... i've had numerous programs segfault and say a core file was written when in fact none was... setting ulimit as needed allowed the core files to be created properly...

There were no cores. I took Mark Lewis' suggestion regarding ulimit and noticed that
the size was set to 0. I changed it to unlimited "ulimit -c unlimited", so next time
I have a segfault, it should generate a core.

Thanks!

I took your advice and set "ulimit -c unlimited". We shall see...

I had done most of these, too, but not all. I made the changes as suggested in the
above wiki entry.

Thanks.
