Yes, to make it clear: the class typeinfo object may have hidden visibility...
it's the __cxxabiv1::__class_type_info "class" that should have default
visibility always.

ok, leaving aside the pedantic issue of whether this is a "regression" or not,
can we get it fixed? I just posted a patch to gcc-patches which allows
dynamic_cast in cases where RTTI is not required, and a

I'm not claiming that the behavior isn't conformant to the docs, I'm claiming
that you regressed a construct that
1) doesn't need RTTI at all (in practice)
2) is used by a major software projec
--- Comment #8 from benjamin at smedbergs dot us 2006-08-11 10:19 ---
The documentation is incorrect. RTTI is not required to find the most-derived
class pointer, because the vtable contains this information natively and does
not need to know anything about the type. I'm maki

Is my summary of how it is done using only the vtable inaccurate?

This cast in particular doesn't need RTTI, because the offset to the most

concrete type for logging purposes, without needing or wanting

Jason, is this a patch that can be safely considered for the 1.4.1/1.4.0
