I finally got at least some swipl running by using the GUI snap installer, which installed 9.2.1
Doing so got me proper behavior for pack_list/1

Interesting. But I see this error not only from pack operations but from other https connections using http_open. When the opened https (vs http) sessions are closed, I see the same errors about system:close_range/3.

Etc..
Works fine here. What is weird is that it tries to call close_range/3 in system. It should do so in the module http_open`.
I don’t have a good explanation. A lot of problems with upgrades to 9.2/9.3 are caused by the fact that many files have changed location and thus installing the new version over an old version causes the existence of both old and new versions of these files. Depending on how you install the system, you may have to wipe the old installation before installing this. This notably applies if you install from source. If you install using the Windows installer, make sure to check the box to wipe the old installation first.
I’m not sure this is the cause here. The range stream that is now use for HTTPS data is in use for many years for Keep-alive connections.
I’m on Mac. I installed (upgraded) swi-prolog from homebrew.
I tried a couple things.
Uninstalled and re-installed with homebrew.
Uninstalled the homebrew version and installed using the installer from SWI-Prolog downloads.
But I still get the same error from both – swipl still tries to call system:close_range/3. The homebrew version uses /opt/homebrew/Cellar/swi-prolog/9.2.1/lib/swipl/library/prolog_pack.pl while the version from swi-prolog.org uses /Applications/SWI-Prolog.app/Contents/swipl/library/prolog_pack.pl, but they cause the same error.
I also tried installing 9.3.1 from swi-prolog.org. Still the same… Sigh…
http_open and close are shown as prolog_pack:http_open and prolog_pack:close. http_open should be coming from the http_open module and close should be built-in. They seem related to the error that I’m seeing.
Maybe the problem is the module http/http_open is garbage collected too early and swipl fails to find http_open:close_range/3? I suspect this because I see a slightly different stack trace sometimes.
Sometimes, the stack trace shows <garbage collected> instead of prolog_pack:http_open('...') in the same place that I pointed to in my earlier posting.
Fixed with a patch to packages/http on the range stream (C) code (use-after-free). This is a rather serious old bug that now becomes urgent I think the brew installer allows installing from the git HEAD. That should fix things for you.
I’ll probably do a re-release of the MacOS binaries.
I installed from HEAD using brew and I can confirm that I don’t see this problem anymore. Thanks again!
