OK, I've gotten almost this far and can bootstrap (the asterisk is actually not the very first char and I have to figure that out). However, in the referenced test case, both typeinfos are apparently merged, thus returning the same pointer for their name strings, so pointer comparison still wouldn't work. Therefore, I guess I'll need to do the following: > You might also need to take steps to ensure that the typeinfo gets emitted > as non-COMDAT with local symbols, so that each object does indeed end up with > its own separate copy. Where should I look to do this? Thanks, Jerry
