Description

Assertion failure: !"_pr_loadmap and lib->refCount inconsistent", at /mnt/ssd1/karl/moz/dev/nsprpub/pr/src/linking/prlink.c:1039

"/mnt/sda11/karl/obj/dist/bin/libsoftokn3.so" is the library involved at

This prevents running mochitests locally, but I guess I can just remove the assert.

regression from https://hg.mozilla.org/mozilla-central/rev/6b285759568c.
Requires clobber to pick up the difference.

Comment 2

[Karl Tomlinson (:karlt)]

Builds from http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-linux64-debug/1407415818/ do not reproduce on my system but local builds from the same revision bf5cbb36f4d2 do, so I guess something in my build config is triggering this.

Comment 3

[Karl Tomlinson (:karlt)]

Removing --enable-system-sqlite removes the error.

libsoftokn3.so does have a dependency on sqlite, but I don't know why that would be relevant here.

Bobby Holley had the same problem today, and after looking at his build, it turns out the problem for him was that nspr was statically linked into nss. I'm curious to know how this happened.

I got the error when i was running mochitests in firefox in Ubuntu 14.04 in my vmware.

http://pastebin.mozilla.org/7314392
In my .mozconfig file,i have:
ac_add_options --enable-debug
ac_add_options --disable-optimize

If you can reproduce more or less reliably, what would be interesting is a full build log (from mach build -v), preferably from a build from scratch.

Added a full build log.

That's a mach build log, not mach build -v :(

Try again after removing /home/royalharsh95/mozilla-central/obj-x86_64-unknown-linux-gnu/security/nss/lib/nss/libnss3.so because your build is incremental and not doing much. (But check the assertion still happens because it might fix it)

Comment 12

[Harsh Vardhan [:royalharsh95]]

This time after removing libnss3.so , I got this:

[Harsh Vardhan [:royalharsh95]]

Should I build from scratch ?

Comment 14

[Mike Hommey [:glandium]]

yes.

Added full build log from scratch :)
