New crasher

[Charles Oliver Nutter]

Ok, call paths are wired up (0-3,N arity w and w/o block) and I'm 
getting a crash running a short benchmark that exercises all the call 
paths. It is attached, as is the hs_err file.

I'll try to narrow it down further and work around it for now.

Run it like this:

JAVA_HOME=../davinci/sources/build/bsd-i586/j2sdk-image/ jruby -J-Xint 
-J-XX:+EnableInvokeDynamic -J-Djruby.compile.invokedynamic=true 
bench_method_dispatch.rb
