Bug #2646: 1.9.2dev segv when compiling with clang 1.1/trunk
http://redmine.ruby-lang.org/issues/show/2646

Author: Ollivier Robert
Status: Open, Priority: Normal
Category: build, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-01-25) [x86_64-darwin10.2.0]

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

[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

make: *** [.rbconfig.time] Abort trap

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