gcc version 4.2.0 20060802 (experimental)
i686-pc-linux-gnu
Code compiled with -fno-rtti containing a dynamic_cast<void*> used to compile
and work properly on types with a vtable (the base class can be determined
entirely using the vtable without any RTTI information). Bug 10891 changed this
behavior to be more strict (too strict). There are additional regressions
listed from that bug; I feel that bug 10891 ought to be backed out. This
materially affects compilation of Mozilla-based products.
Testcase forthwith.
