Update: I'm happy to report @dartonw 's answer worked and I went and did a checkout and then buildworld and it built successfully in about 6 hours.
So I've been having some issues with jails in freebsd. I run FreeBSD9.1 64 bit on EC2 as a small instance. I recently tried :
cd /usr/src;make buildworld
And after nine hours of compiling it gives me :
{standard input}:12044: Warning: end of file not at end of a line; newline inserted
{standard input}:12142: Error: invalid character '_' in mnemonic
c++: Internal error: Killed: 9 (program cc1plus)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I came across this article which says :
Let's synchronise sources.
# cd /usr/share/examples/cvsup/
# cp standard-supfile /etc/freebsd-supfile
The list CVSup mirror sites is here.
But, the link says:
Warning: cvsup has been deprecated by the project, and its use is not recommended. Subversion should be used instead.
What should I do then? Where can I find an updated article? Should I update my ports collection?
