Yeah, I have the same problem, as I also build and install as non-root. 
Outside chroot, ptys work with no problems as both root and non-root, 
but inside chroot ptys work fine as root but not as a user. This seems 
to have happened due to the switch from Glibc to EGLIBC (I simply go to 
my build script and change "eglibc" to "glibc" and suddenly ptys work as 
a user), though I have no idea about the specifics.

Unfortunately I also have no idea about a solution, but then I haven't 
really tried that hard as I generally don't run testsuites much anyway. 
I've googled for a fix, and the closest thing I can find is a Debian 
patch - 
http://changelogs.ubuntu.com/changelogs/pool/main/e/eglibc/eglibc_2.9-20ubuntu2/changelog 
(the "unlockpt" one) - which according to further searching seems to be 
just modifying [glibc source]/sysdeps/unix/bsd/unlockpt.c and changing 
"sizeof (_PATH_TTY) + 2" to just "1024". I can't find anything else on 
the details of exactly what problem it's supposed to fix so I really 
have no idea whether it even has anything to do with root/non-root 
permissions issues, but it's worth a try I guess, unless someone has a 
better solution...
