Stack Smash from Wesnoth 1.14.13 (Debian)

Post by Voland0W »

After upgrading from 1.14.5 to 1.14.13, starting Wesnoth fails with a report of a detected stack smashing:
~$ wesnoth

It doesn't display the UI, so I am not able to get the build information, as directed on the How to Report a Bug Properly topic.

Reading the bug report on the Debian website, I learned that Wesnoth can be started with `wesnoth --nocache`. Upon doing that, I could get the build information:
The Battle for Wesnoth version 1.14.13

Second Update: Upon further reading of the Debian bug report, it looks like a mismatch between libwolfssl versions or the headers. See ... bug=970520

Third Update: I down-graded libwolfssl from 4.5.0 to 4.4.0, and Wesnoth starts up normally, now. I may ought to change the post title to Upgrade libwolfssl in Build, or something like that. ... Oh, that doesn't seem to be an option.

Wesnoth doesn't use wolfssl itself - that's a change Debian made since openssl's license prior to version 3 isn't compatible with the GPL - it uses openssl. As far as we're concerned though, the license incompatibility problem will solve itself once openssl 3 is made available, so any problems caused by wolfssl would need to be solved by Debian as well.
