[solved] Firefox 29.0.1 fails to start, GLIBCXX_3.4.20 not found

Following up on this post: [solved] Firefox 29.0.1 missing dependency for glibc by alex3772

I experience the same issue, firefox fails to start with this error:

XPCOMGlueLoad error for file /usr/lib/firefox/libxul.so:
/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /usr/lib/firefox/libxul.so)
Couldn't load XPCOM.

But contrary to the previous post, I'm running the up to date kernel.

% uname -a
Linux hostname 3.14.4-1-ARCH #1 SMP PREEMPT Tue May 13 16:41:39 CEST 2014 x86_64 GNU/Linux

At first I thought this was a fluke to be fixed shortly but it's been a few days now and the previous post is the only mention I've found of this issue.
It seems on my laptop libstdc++.so.6 update didn't go according to plan last time gcc-libs got updated.

What happens if you simply try to reinstall gcc-libs (perhaps with pacman's debug flag to see if anything fails)?

# pacman --debug -Syu gcc-libs

Burninate!

Thanks for the advice, it worked.

I wonder what happened, is there a way to check if there is something wrong with other packages ?
