cvsup{,d} woes after upgrading to RELENG_9 on amd64 this weekend

[Trond Endrestøl]

Hi,

After upgrading to RELENG_9 as of yesterday on my amd64 system, cvsup 
bombs out with Bus error: 10.

Example:

# /usr/local/bin/cvsup -g -L 2 /usr/src/stable-supfile
Parsing supfile "/usr/src/stable-supfile"
Connecting to localhost
Connected to localhost
Server software version: SNAP_16_1h
Negotiating file attribute support
Exchanging collection information
Establishing multiplexed-mode data connection
Running
Updating collection src-all/cvs
Bus error: 10

The only recent change I can think of is switching to clang for 
building the kernel and base. Made I should rebuild world and kernel 
using gcc.

Today, I used portupgrade -fprv lang/ezm3 net/cvsup-without-gui, but 
cvsup gives me the same result as in the example above.

This bug also affects cvsupd for those of us who are running a local 
FreeBSD CVSup mirror (http://motoyuki.bsdclub.org/BSD/cvsup.html) on 
amd64/RELENG_9.

I know csup is generally preferred over cvsup, and in the meantime I'm 
able to use csup with another local FreeBSD CVSup mirror running on 
i386/RELENG_8.

cvsup on the amd64 box crashes with Bus error even when accessing the 
CVSup mirror on the i386 box, thus indicating a problem local to the 
amd64 box.

I welcome any clues to solve this problem.
