Hmm, try this line

  const serverIdl::MessageUnit &msgUnit = msgUnitArr[i];

in 

  xmlBlaster/src/c++/client/DefaultCallback.h:109

instead of the old line, possibly it helps.
If it fixes the bug please commit to cvs.

No idea.

Mine works (all clients work).

Thanks

This warning occures during gmake, is it possible to
suppress it?:

 /bin/mkdir bin
/bin/mkdir: Can't create directory »bin« : Exists already
make[2]: [link] Error 1 (ignored)

and all client executable exist double, one
in xmlBlaster/testsuite/c++ and
one in xmlBlaster/testsuite/c++/bin

Marcel
