Problem with exception handling on SunOS 10

[eladouc]

Hi

I'm getting a strange problem and I can get over it.

1 - I have a library (libcppbase.so) that implements a class DMUString.
2 - I have a library (libKVSlibrary.so) that implements HFSFileWrap with Open method that throw DMUString object as exception
3 - I have a third library (libCAAV5ModelIO_TDM.so) that calls HFSFileWrap.Open and try to catch the DMUString exception, but it always go in the general exception handler : catch(...)

I have this behavior only on SunOS. With the same code, on AIX or HP, it's working.

If I try to throw and catch HFSFileWrap instead of DMUString, it works...

libCAAV5ModelIO_TDM.so is a CAA library build for Catia...

In libcppbase.so

class DMUString
{
};

In libKVSlibrary.so

class HFSFileWrap
{
void Open()
{
throw DMUString("My exception");
}
};

In libCAAV5ModelIO_TDM.so

HFSFileWrap fw;

try
{
}
catch(DMUString& e)
{
//That's where I would expect the code to go
}
catch(...)
{
//That's where the code actually go
}

Does anybody have a clue on what could be the problem ?

Thanks

Eric

Maybe this explains things?
