Links upstream says if you find a bug:

Send bugreport to the following four addresses:
mikulas at twibright.com
brain at twibright.com
clock at twibright.com
perm at twibright.com
Bugreport should include how to invoke the bug, what version you have got, what operation system do you run Links, and if you know it, then also what capabilities have been compiled in Links.
If Links segfaults, then look if you got the core. If not, switch the coredump on with "ulimit -c unlimited" and segault links with the bug one more time. Then archive the core. Do not send the core as an attachment.

Well, it's a downstream issue.
The same version works fine on Fedora…

Comment 3 Thierry Vignaud 2020-03-30 15:10:27 CEST

Humm interestingly it works with some local accounts and not with others…

Comment 4 Thierry Vignaud 2020-03-30 15:11:20 CEST

It happens when parsing ~/.links/links.cfg…

Comment 5 Thierry Vignaud 2020-03-30 15:21:16 CEST

OK, for any accounts, links will segfault on any site, providing you:
* save settings (<esp>, then <Esp> Setup>Langage>French)
* quit
* restart links

Whatever the langage is (tested with both English & French)

The same works fine on eg Fedora

Comment 6 Thierry Vignaud 2020-03-30 15:29:07 CEST

Disabling patch 23 (links-2.15-dont-have-two-assocations-with-same-label--otherwise-one-cant-override-shared-config.patch) fixes that…

This one is a very old one:

* Sat Oct 08 2005 Pixel <pixel@mandriva.com> 2.1-0.pre18.6mdk
  - don't have two assocations with same label, otherwise one can't override shared config

Comment 7 Thierry Vignaud 2020-03-30 15:44:42 CEST

links-2.14-1.mga6 was good
links-2.19-1.mga7 was broken

There's nothing standing out in the 2.15 rediff but I'll dig further…
