Problem with static link with gcc-3.4.2 : typeinfo for ...: discarded in section .gnu.linkonce.r._

[Evgenia Abramov]

Hi,

I use compiler gcc-3.4.2 on EM64T machine.

One of my static compilation ( shared link passed OK) I receive several errors like the following:

typeinfo for UcmNetOcc: discarded in section `.gnu.linkonce.r._ZTI9my_symbol' from /tmp/outdir/libXX.a(X.o)

Where the library /tmp/outdir/libXX.a and also the object X.o contain the following reference to my_symbol:
> nm /tmp/outdir/libXX.a | grep ZTI9my_symbol | c++filt
0000000000000000 V typeinfo for my_symbol

Does anybody know what is wrong here? What does this error message mean?

Additional data on my build environment:
