Bug 268516

I tried rebuilding profanity and it's still segfaulting.

Could you please rebuild profanity with debug symbols enabled, i.e. -DWITH_DEBUG:

  % sudo make -DWITH_DEBUG -C /usr/ports/net-im/profanity clean build deinstall reinstall clean

And then run it under a debugger (gdb, or lldb):

  % gdb $(which profanity)

  (gdb) run
  ....

  (gdb) bt all

OR:

  % lldb $(which profanity)

  (lldb) run
  ....

  (lldb) bt all


And share the output here. That'll help with what's causing the problem, as I don't have a 12.x host to test it out.

And could you please also share the output of: pkg info -a

Thanks!

Hi!

Let me start with the backtrace. Let me know if this helps or not.

Thanks!

I'm trying to downgrade readline, but am having an issue. It seems like it might be a pkgng bug.

You need to do: sudo pkg add -f ./package.pkg

Thank you! It's readline! 8.2.0 segfaults, 8.1.2 is fine.

If I build readline 8.2.0 from ports, it also segfaults.

This works on FreeBSD 13.1, so seems it may be just 12.3. Even with readline 8.2.0.

With FreeBSD 12.x EOL, I am marking this as overcome by events. Thank you!
