ICE at objc-parse.y:339 (current CVS): GGC?

[Andreas Jaeger]

With yesterday's CVS (update at 16:00 UTC 19991107) I managed to get a
full three stage bootstrap will all frontends.  But build failed after
25hours in libobjc.  It looks like a garbage collector problem since
declspec_stack has beeen garbage collected.
