while running emerge @world, I ran into the following issue.

(while running emerge -e @world, I should say. :)
Does it happen on system with nvidia video card, perhaps ? I am asking because I have two Gentoo systems - one with nvidia card, and other with AMD APU. I encountered this error a while ago, but ONLY on NVIDIA proprietary drivers. More than that: if I select xorg opengl (eselect opengl set xorg-x11) the hang out is gone.
Please post your `emerge --info' output in a comment.
No, both systems are intel video chips only.

yes, this is long issue that pops up randomly... see at least bug#214578, bug#131234.
Intel VGA (Core i3 built-in). Bug confirmed during world rebuild. 3 days in progress... killed it.
I found something and it works: - switch to a tty and remerge pth there https://www.mail-archive.com/blfs-support@linuxfromscratch.org/msg19350.html
I can confirm that switching to a tty (i.e., ctrl-alt-f2) before emerging makes this go away. Not sure why.
Got it for the first time, with the newest gcc 4.8; it worked a few weeks ago with gcc 4.7
(In reply to Arnaud Launay from comment #12) > Got it for the first time, with the newest gcc 4.8; it worked a few weeks > ago with gcc 4.7 can you always reproduce this?
Yes, but I just tested with gcc 4.7, it stalls also with it. 100% percent reproducible with gcc 4.7 and 4.8, then. Kernel and most of world have been recompiled with 4.8 in the meantime, though. I'll try to recompile the kernel (and maybe glibc) with 4.7.

can other confirm that they are using gnome shell?
(In reply to Alon Bar-Lev from comment #20) > can other confirm that they are using gnome shell? I can. gcc 4.8 emerging pth in gnome-terminal hangs, running from other tty runs OK. also sending sigterm to the hung process makes the installation continue.
