Happened to me also.
Comment by Judd Vinet (judd) - Sunday, 13 February 2005, 19:38 GMT
That's strange. Why was pacman removing nss-nspr, then re-installing it?
Comment by Askadar (askadar) - Sunday, 13 February 2005, 20:11 GMT
Don't know. I did not specify any further options. I have a vanilla pacman.conf .
Comment by Jan de Groot (JGC) - Monday, 14 February 2005, 08:59 GMT
Hmm, mozilla conflicts with nss-nspr now, and nss-nspr had an upgrade. Seems pacman upgrades it, even when it's conflicting.
Comment by Jan de Groot (JGC) - Monday, 14 February 2005, 10:13 GMT
This segfault stuff seems to happen when a lib moves from prefix. I've seen the same with gnome-terminal when vte moved from /opt/gnome to /usr.

I had that segfault, too. It complained about that readline thing before, too.
Comment by Simo Leone (neotuli) - Sunday, 03 April 2005, 02:42 GMT
I've been seeing that readline complaint a lot lately.

I too received my first pacman problems today.

1) Kept seeing "error: anonymous login failed"
2) Segfault after everything's been installed.

nss-nspr package features here too. Here's the output:

If anyone can reproduce this reliably, please send me the gzipped-tarball of your /var/lib/pacman directory.
Comment by Dale Blount (dale) - Tuesday, 19 April 2005, 19:22 GMT
Just a hunch, but it seems to me it only happens on a "desktop" type install. I'm not sure if that's because of the number or the type of packages installed, but I've seen it on just all (I think) of my systems with X (4) and none (that I can remember) without (70ish).

I'm not saying that it's X, but more likely something mozilla or nss-nspr based. My attempts to reproduce the bug failed.
Comment by Judd Vinet (judd) - Thursday, 21 April 2005, 22:09 GMT
Found (and fixed) the problem. It had to do with the hash table caching of db_scan() calls. When a package was removed (or replaced) the hash table entry was not removed. So when a sync was propagating requiredby fields to the new packages, it segfaulted when referencing the old package.

Will be fixed in 2.9.6
