Openoffice doesn't work with kernel+world built with Clang

I have a 9.0-current (r214167) amd64, kernel and world built
with clang and all ports built with gcc, and i cannot start
openoffice anymore, it shows splash, start to go up and die.

If I reinstall world+kernel built with gcc openoffice works fine.

The is a ktrace result available [1], let me know if you need
more information or tests.

Thanks
