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.
