[omniORB] omniORB 4.1.x and Microsoft VC7.1 compiler

[Barthel, Marco (Marco)]

Hi,
is anybody out there using omniORB 4.1.3 and microsoft's VC7.1 compiler?
We are experiencing problems when counting the reference via functions like

ABSORB_API void ABSORB_IncRef(PortableServer::Servant servant);
ABSORB_API void ABSORB_DecRef(PortableServer::Servant servant);

somehow the compiler seems to generate incorrect code (looks like a problem with multiple inheritence)

There are two occurences of "omniServant" one of it is corrupted/strange.

Strange. How is your servant class defined?

Cheers,
