ICEs with -fobjc-gc -fgnu-runtime (works without -fobjc-gc or with -fobjc-gc
-fnext-runtime).  Apparently objc_assign_ivar_fast_decl and
objc_assign_ivar_decl are only initialized for next runtime, but are used
unconditionally even for GNU runtime.

-fobjc-gc should error out for the GNU runtime.

It was already fixed in trunk; I added the assert too.

Thanks

Yes, this is already fixed in trunk.  It would be good to add a

  /* This is currently only used with the next runtime.  */
  gcc_assert (flag_next_runtime);

at the beginning of objc_build_ivar_assignment () to make really sure it can
never happen. ;-)

Thanks
