Hi Gustaf,

Have you fixed or considered fixing this issue?

Hi Ben,

we have discussed this here, but we have not released any code in this direction yet. The included patch will be in 1.3.7 and prevents overwriting of objects through new.

cd xotcl-1.3.6 patch -p0 < /tmp/new-patch

best regards -gustaf
