Subject: trunk & llvm-gcc 4.2

Hello,

I've been trying to compile ruby 1.9/trunk with llvm for some time
(llvm-gcc 4.2 as shipped by Apple in XCode 3.1.1) and always hit the
same problem.  During the compilation, first time miniruby tries to run,
it goes into a never-ending loop.

Running Shark on the process give the following call stack (see the
linked image).  -O or -O2 does not make any difference.

...
./miniruby -I../lib -I.ext/common -I./- -r../ext/purelib.rb
../enc/make_encdb.rb encdb.h.new ../enc enc
load: 1.23  cmd: miniruby 3505 running 3.64u 0.03s   (after pressing ^T)
load: 1.11  cmd: miniruby 3505 running 62.80u 0.53s  (^T again)

Thanks for your attention.

MacOS 10.5.5, Xcode 3.1.1, Ruby trunk at #19642.
