Cannot catch exceptions on 64bit.

[benjamin . bihler]

Hi,

if I throw an exception in a shared library it cannot be caught in the
same library. The code for throwing the exception is

throw new TWTMeshingLib::Utils::CTWTException( "Vector length is
zero!", __FUNCTION__, __FILE__, __LINE__ );

and the catching code is

try {...}
catch (TWTMeshingLib::Utils::CTWTException *e)
{...}.

The program was compiled with g++ 4.1.2 on an OpenSUSE 64bit system
and on a Debian 64bit system. The exception can be caught, if the
library is linked statically and it can always be caught on 32 bit
systems. So probably the code itself is correct.

Is this a known problem? What can I do to catch exceptions within a
dynamic library on 64 bit systems?


Thank you very much,
Benjamin
