g++ and dynamic_cast

[Mihai Donțu]

Hi,

Assuming I have a program that loads two shared objects (liba.so and libb.so), 
is there any way that I can make dynamic_cast work in libb.so for an object 
obtained from liba.so, without loading liba.so and libb.so with dlopen(...|
RTLD_GLOBAL)?

Currently, dynamic_cast returns NULL if the shared object (plugin) is loaded 
with dlopen("liba.so", RTLD_LAZY) (some rtti nastiness).

I'm using gcc 3.2.2 and I can't update to gcc 4.x.

Thanks,
