>Description:
rsync port core dumps tansferring large files if you use -z/--compress option.(Problem does not occur if you install manually from source.) I made a basic rysnc port Makefile (no patches/options etc) and it still coredumps.
Here's a gdb from a normal port install that was tweaked to enable debug symbols:
Program terminated with signal 11, Segmentation fault.
Reading symbols from /usr/lib/libc.so.4...done.
Reading symbols from /usr/libexec/ld-elf.so.1...done.

>How-To-Repeat:
transfer a large (binary?) file with compression on. local to local transfers also fail.
