Alright, I run into this again while emerging qtwebengine on Gentoo.
Now I think about it, this is the only and systematic cause of the issue
for me.
I suspect that emerging / compiling Chrome or affiliated projects would
also trigger the issue.
This time I managed to save the output, 60M+ big.
I tried to following
- emacs -Q
- M-x eshell
- cat portage.output.log
It took about 2 hours to complete! While it takes half a second to
paste to the buffer.
Damn! Eshell's filters are slow! :/
That being said, no issue doing that. So the output "saved after the
fact" does not seem to produce the issue.
