Created an attachment (id=3304)

Testcase code that causes internal compiler error, reduced as per:
http://llvm.org/docs/HowToSubmitABug.html

While using llvm-gcc to compile some code that uses Objective-C 2.0's fast
enumeration, I encountered an internal compiler error.

I am running a version of llvm-gcc that I built from the svn repo, revision
78845.  I fully recompiled both llvm and llvm-gcc using this revision number.

The command I am using, under Ubuntu 9.04, to compile the testcase-min.mi file
that I've attached is:

/usr/local/bin/gcc -I/usr/include/GNUstep testcase-min.mi

and the error is:

internal compiler error: in objc_build_foreach_components, at
objc/objc-act.c:19778
