--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This restores the missing symbol:
--- a/libstdc++-v3/libsupc++/cxxabi.h
+++ b/libstdc++-v3/libsupc++/cxxabi.h
@@ -300,7 +300,7 @@ namespace __cxxabiv1
virtual bool
__pointer_catch(const __pbase_type_info* __thr_type, void** __thr_obj,
- unsigned __outer) const = 0;
+ unsigned __outer) const;
};
// Type information for simple pointers.
But I don't know why it was made pure.
Jason, was the change from inline to pure necessary to fix a failure?
The function is still defined as inline in libsupc++/tinfo.h

--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Defining the function inline means that cxxabi.h depends on our implementation
details, which makes it incompatible with other implementations of the ABI
(libc++ uses our cxxabi.h but provides their own definitions of the public
interface).
Should this be reopened?
