Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |wjwray at gmail dot com --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- This was caused by the patch for PR 87364 (r265077 and r265078). Presumably GDB can no longer recognise the RTTI for shared_ptr because the demangled name no longer looks like (__gnu_cxx::_Lock_policy)2. The patch breaks existing functionality. Looks like it was not sufficiently tested.
