As I've been doing for several months/years, I'm compiling regular snapshots of the clang compiler and use it to compile ruby/trunk.
I have clang@94309 and ruby 1.9.2dev@26404 on OS X 10.6.2. For several revisions of ruby I get this when running miniruby during the build process:

clang -O -m64 -g -pipe -I. -I.ext/include/x86_64-darwin10.2.0 -I../include -I.. -DRUBY_EXPORT -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -o newline.o -c newline.c
clang -O -m64 -g -pipe -L. -m64 -g -L/usr/local/lib -Wl,-u,_objc_msgSend main.o dmydln.o dmyencoding.o miniprelude.o array.o bignum.o class.o compar.o complex.o dir.o enum.o enumerator.o error.o eval.o load.o proc.o file.o gc.o hash.o inits.o io.o marshal.o math.o node.o numeric.o object.o pack.o parse.o process.o random.o range.o rational.o re.o regcomp.o regenc.o regerror.o regexec.o regparse.o regsyntax.o ruby.o safe.o signal.o sprintf.o st.o strftime.o string.o struct.o time.o transcode.o util.o variable.o version.o compile.o debug.o iseq.o vm.o vm_dump.o thread.o cont.o ascii.o us_ascii.o unicode.o utf_8.o newline.o dmyext.o -lpthread -ldl -lobjc -o miniruby

Any idea/test I could ru to see whether it is a clang-related issue or a ruby one?

I'm not familiar with "clang", but if it has the equivalent of gdb, you could try running it in that, and/or valgrind.

Hmm, it seems your clang's bug.
I can compile with clang 1.1 with x86_64 FreeBSD.

Anyway, it seems crash of miniruby.
Can you try following?
gdb ./miniruby -e'1'
