Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-SW-Source: 2010-q1/txt/msg00011.txt.bz2 I'm hacking on bz 9629 "GDB fails to display the base class through the derived class if the derived class contains more than one vptr for virtual function." http://sourceware.org/bugzilla/show_bug.cgi?id=9629 One of my guesses of the moment is that under the circumstances of the bug, the "vtable" is either being built wrong or is somehow being corrupted--does anyone have a clue where the "vtable" is built? I'd've thought in dwarf2read.c, but if it's there it's not obvious (at least to me...). Another guess is that in gnuv3_baseclass_offset, gnuv3_get_vtable is being called with a bad type argument, but I haven't looked into that yet. Thanks, Chris
