Should be easy enough to debug:

$ cc -g3 -ggdb -o svnup svnup.c -lmd
$ gdb svnup
(gdb) run -h svn0.us-west.FreeBSD.org -b ports/head -l test

Then once it cores, provide the output from "bt" and/or "bt full".

Might also be useful to compile with -Wall to see if there are any
compile-time warnings.
