shared libs and dynamic_cast bug in OpenServer?

["Arturo Montes" <mitosys at colomsat dot com dot co>]

Hi

I am using egcs-1.1b on OpenServer 5.0.4 and to run the example simple type:

build.sh

It build program A and build B and C shared libs.

Simply type:

A

You must get B=xxxxx valid memory address, but dynamic cast fail returning
0.


However, if dlopen is executed with RTLD_GLOBAL flags, it work ok. This is
not a bad behaviour? I guess this depend of rtti not put in shared libraries
if not in a executable program.

Thanks

Arturo
