Ok, please do the following:
run cvsup under the gdb. When SIGSEGV is raised, from the gdb prompt, do:
1. info registers $rsp
2. info program
This should print you the pid of the process, then do
3. shell procstat -v <pid>

Also, you might try to test my guesswork, by adding the following
patch to lang/ezm3 and rebuilding it, then rebuilding cvsup port:
[made a file below ezm3/files, cleaned the workdir, reinstalled it
cleaned cvsup, rebuilt it]
no change so far
